 Edit ems_home.html . This can be as simple as a couple of lines of HTML, for example: 
 <h1>Snow Leopard LTD</h1>
<h2>Rooms to join</h2>
<ul>
 <li><a href='/#/room/#welcome:snowleopard-staging.ems.host'>Welcome to Demo web chat (#welcome)</a></li>
 <li><a href='/#/room/#support:snowleopard-staging.ems.host'>Support (#support)</a></li>

 Edit ems_welcome.html . This is a bit more complex, but it can be almost anything you want as long as it has links to Log in ( /#/login ) and Create account ( /#/register ). The default design is based on this template . You can get creative with the CSS and the !important tag.

 Serve the files 
 You must host the files somewhere where they are publickly accessible and you need to enable the CORS header Access-Control-Allow-Origin: * on the web server for these files. See https://enable-cors.org/ for instructions on how to do this. 
 Configure your EMS server 
 
 
 Add the URLs to the Client look & feel section in the EMS Control Panel. Click Save . 
 
 Unfortunately, we have a bug in the validator affecting files hosted on Matrix. Just ignore the error. 
 
 Note if you are hosting the files on your own web server, you only need to change your EMS server configuration or reprovision if the URLs have changed. Changes to the contents of existing files are applied automatically 
 
 
 
 Once your host finishes reprovisioning, check your Element Web to ensure the changes are applied correctly.

EMS Server With Custom Domain
For this guide, I will be using the domain
 element.io . I will set up EMS so that the
Matrix usernames becomes @someone:element.io , and the Element client will be at
 https://chat.element.io/ 
 From the guide at Get Your Own EMS Server , I will be replacing the EMS hostname
 ems-demo-staging.ems.host with element.ems.host 
 Custom domains are only supported with Element Enterprise Cloud plans. 
 Prerequisites 
 
 You own and control the domain you want to use 
 If you do not have a website on the domain you want to use with your EMS server:
 
 You can create a CNAME DNS record for the domain. Some providers call this ALIAS or CNAME Flattening when used on
the root of the domain (domain root = yourdomain.com , not something.yourdomain.com ) 
 
 
 If you have a website on the domain you want to use with your EMS server:
 
 Your website has HTTPS enabled using a valid certificate issued by a commonly recognized provider. For example,
Comodo or LetsEncrypt. 
 You can serve plain-text JSON files at these exact paths
 
 
 https://yourdomain.com/.well-known/matrix/client 
 
 
 https://yourdomain.com/.well-known/matrix/server 
 
 Note that these files do not and cannot have a file extension 
 
 
 You can add the header Access-Control-Allow-Origin: * to the client file on the web server 
 
 
 
 See also 
 
 
 FAQ: Can I use a subdomain instead of the root domain with my EMS server? 
 
 
 FAQ: Can I use EMS-hosted well-knowns with the root of my domain? 
 
 
 Setup 
 Some providers for DNS and website hosting providers need special configuration. See
 Provider specific instructions at the bottom for known solutions. 
 
 
 Follow steps 1 - 10 from Get Your Own EMS Server 
 
 
 On step 10 from Get Your Own EMS Server , turn ON Custom DNS 
 
 
 
 In the Custom Homeserver domain field, enter element.io 
 
 
 
 Create two files on your website according to the instructions given. 
The path cannot be changed, but up to 30 redirects are supported. 
While not required, you should add the header Content-Type application/json to both files. 
 
 
 https://element.io/.well-known/matrix/server 
 
 {
 "m.server": "element.ems.host:443"
}
 
 
 
 https://element.io/.well-known/matrix/client 
 
You need to enable the CORS header Access-Control-Allow-Origin: * on the web server for this file. See
 https://enable-cors.org/ for
instructions on how to do this. If you are using redicrects, the CORS headers must be set on all steps/hops. 
 {
 "m.homeserver": {
 "base_url": "https://element.ems.host"
 },
 "m.identity_server": {
 "base_url": "https://vector.im"
 },
 "org.matrix.msc3575.proxy": {
 "url": "https://element.ems.host"
 }
}
 
 
 
 
 Optional Nginx-specific configuration 
 If your web server is running Nginx, you can set this in the Nginx config instead of creating actual files. 
 server {
 server_name element.io

 ...

 # Matrix well-known files
 location /.well-known/matrix/client {
 return 200 '{"m.homeserver":{"base_url":"https://element.ems.host"},"m.identity_server":{"base_url":"https://vector.im"},"org.matrix.msc3575.proxy":{"url":"https://element.ems.host"}}';
 add_header Content-Type application/json;
 add_header 'Access-Control-Allow-Origin' '*';
 }
 location /.well-known/matrix/server {
 return 200 '{"m.server": "element.ems.host:443"}';
 add_header Content-Type application/json;
 }
}
 
 
 
 
 Click Check again to verify that your .well-known files are configured correctly 
 
 
 You can also verify your `.well-known` files from the command line 
 Note the lines access-control-allow-origin: * and content-type: application/json

 You can continue without the .well-known files in place, but your server will have limited functionality until this is fixed 
 
 
 In the Custom Client domain field, enter chat.element.io . This can be any domain, except the same as Custom Homeserver domain 
 
 
 
 Create a CNAME DNS record with your DNS provider according to the instructions given 
 chat.element.io. CNAME element.element.io. 
 
 
 
 This shows how this is done with Cloudflare DNS. Depending on your DNS provider, this might be different. Consult the
documentation for your provider. Note that Proxy must be turned off with Cloudflare. 
 
 
 
 Back on EMS, click Check again . Note that sometimes it might take a while for your new DNS record to propagate.
You can continue, but functionality will be limited. Check back with the Hosts tab on
 https://ems.element.io/user/hosting 
and click Rebuild Host once the DNS record is in place. 
 
 
 You can also verify the CNAME DNS record using the command line 
 
 
 On Mac or Linux, using the terminal

 Provider-specific instructions 
 GitHub Pages 
 If you are hosting your website with GitHub Pages, add this to the Jekyll config file _config.yml 
 include:
 - .well-known
 
 Microsoft Azure 
 If you are using Microsoft 365 / Azure to manage your domain or the rest of your infrastructure, please use the following instructions to host the .well-known/matrix URI (RFC 8615). 
 In this section, we will configure Azure to serve https://yourdomain.com/.well-known/matrix/client and https://yourdomain.com/.well-known/matrix/client . 
 The summary of steps is as follows: 
 
 prepare json files 
 create a Storage account then enable a Static website 
 upload the json files to .well-known/matrix/ in the $web container 
 create a CDN and an endpoint for this container 
 create a CNAME DNS entry for your custom domain, pointing to your CDN endpoint 
 associate your custom domain to your CDN endpoint 
 
 Prepare client and server .well-known files locally 
 On your computer, prepare two plain text files called client and server (again, notice the lack of file extension such as ".txt") which contain the following: 
 client 
 {
 "m.homeserver": {
 "base_url": "https://your-tenant.ems.host"
 },
 "m.identity_server": {
 "base_url": "https://vector.im"
 },
 "org.matrix.msc3575.proxy": {
 "url": "https://your-tenant.ems.host"
 }
}
 
 Remember to replace your-tenant by the name of your EMS tenant. 
 server 
 {
 "m.homeserver": {
 "base_url": "https://your-tenant.ems.host:443"
 }
}
 
 Remember to replace your-tenant by the name of your EMS tenant. 
 You will be uploading these shortly. 
 Create a Storage account and Static website 
 Storage account 
 In the Azure Portal, create a Storage account . 
 
 The name needs to be unique to Azure. yourdomainwellknown is an option that should work well in most scenarios. 
 Performarce can be left to Standard. 
Redundancy should be set to Geo-redundant storage (GRS) as the .well-known URI will be a core part of your EMS deployment. 
You can leave all other options to their default or change them to fit your specific deployment scenario. 
 Finally, click create. 
 Static website 
 Once the Storage account is created, you will need to create a Static website in this Storage account. 
In the Storage account overview, choose "Static website", in the Data management section. 
 
 You do not need to provide a specific Index document name or Error document path. 
 Enabling the Static website in your Storage account will automatically create a $web storage container to which you can upload the json text files which will be served at the .well-known URI. 
 Go to "Containers", in the "Data storage" section, to upload the client and server files you prepered earlier. 
 Click on the $web container, then chose "Upload", which will open a panel on the right. 
 When uploading the client and server files, make sure to open the "advanced" part of the upload panel and choose to upload to a specific folder: .well-known/matrix/ 
 
 Create a CDN, CNAME DNS entry for your custom domain and Custom domain name for the CDN endpoint 
 Creating a CDN is needed because Azure does not allow serving HTTPS over a custom domain using only a Storage account Static website. To do so, a CDN is necessary. 
 Create a CDN endpoint 
 Go back to your Storage account's main view and choose "Front Door and CDN" in the Security + Networking section, to create a CDN endpoint. 
 
 Service type: Azure CDN is sufficient, the more advanced features of Azure Front Door are not necessary here. 
 If you need to create a new profile, you may call the Profile name and Endpoint name as you wish. 
For consistency, it is suggested to call them yourdomainwellknown as previously. 
 For Origin host name, pick your Static website. 
 For Query string caching behaviour, pick Ignore Query String, although this setting is not important in our context. 
 Once your endpoint is deployed, go to the resource, then go to your endpoint's further settings by clicking on it. Make note of its hostname ( rfc8615demo.azureedge.net in our example) as you will need it shortly. 
 
 Create CNAME DNS entry for your custom domain 
 You will now create a DNS entry for your custom domain, a CNAME pointing to your Azure CDN endpoint's hostname. How to do so exactly will depend on who hosts your DNS servers. The specifics of this are beyond this documentation, but the following general information should be sufficient. 
 In your DNS provider's admin panel, add a DNS entry with the following details: 
 
 Type: CNAME 
 
 Domain: your custom domain, such as yourdomain.com 
 
 Target: your Azure CDN Endpoint's hostname, such as rfc8615demo.azureedge.net in our example 
 
 Once created, this DNS entry may take some time to propagate, but in most cases will be picked up quickly by Azure, as needed in the next step. 
 Associate your custom domain with your CDN Endpoint 
 In the endpoint's settings, choose "+ custom domain" to start adding your custom domain. A panel will open on the right. 
 Enter your custom domain: yourdomain.com and finally, click add. 
 If the CNAME entry can be seen by Azure, after a few minutes your custom domain should be associated with your CDN Endpoint. 
 Final result 
 https://yourdomain.com/.well-known/matrix/client and https://yourdomain.com/.well-known/matrix/server are now served over HTTPS by Azure. 
 You should now have the following resources in your Azure account: 
 
 Storage account 
 Front Door and CDN Profile 
 Endpoint

Migrate From EMS to Self-Hosted
For support on Synapse or matrix-media-repo, ask in the Matrix rooms #synapse:matrix.org and #mediarepo:t2bot.io . For support on bridges, see the bridge documentation for each bridge's support channel. 
 See also this excellent blog post by Robin Riley at The Matrix.org Foundation. 
 Important 
 
 It is impossible to change the domain of any Matrix server. Therefore if your EMS server is not using Custom DNS (i.e. your Matrix IDs are @someone:hostname.ems.host ), unfortunately it is not possible to import your export to your own or another environment.
 
 You can run an export with this domain in a local environment if you set up your own DNS and self-signed certificates. But you will not be able to federate with the public Matrix federation. 
 
 
 Do not cancel your EMS server until you have downloaded your export and verified its content. Canceling your server will erase your data. 
 You will experience some downtime as your server will be stopped while the export is running. The EMS export tool will estimate the actual downtime when initiated. 
 Ensure all your users have key backup configured and working before starting the export and migration. All clients need to log out and in again after the migration. See the Cross Signing section for more information about key backup. 
 It is impossible to read encrypted messages or media from the export. Encrypted data in Matrix can only be decrypted by the user in their client when they have the required decryption keys. 
 
 Export data 
 
 Go to https://ems.element.io/user/hosting#/exports 
 
 Select the server you want to export from in the drop-down box, then click Create export 
 
 Wait for the export of your config, database, and media to complete 
 Once all exports have completed, download all files provided 
 
 Import process 
 For all components, you must install the same version as your EMS server is running. Version information is provided in the hostname-config.md file. If a newer version is available, once the import is completed and verified, follow the official upgrade documentation for each component to upgrade. 
 All required configuration values are provided in the hostname-config.md file. 
 
 Following official documentation, install and configure
 
 
 PostgreSQL . Refer to the Synapse PostgreSQL documentation for database setup 
 
 Synapse 
 
 Optional (see media step below): matrix-media-repo 
 
 
 
 When generating your Synapse configuration file, you MUST use the same domain as your EMS server 
 Do not start Synapse yet 
 In the Synapse config file (usually homeserver.yaml ), set:
 
 
 pepper . If you do not do this, you have to reset all passwords 
 Signing key. This is stored in a file. See this config file option for path. Alternatively, add the public key for your EMS hosted server to old_signing_keys . If your EMS server is still running, you can find your public signing key at https://yourHostname.ems.host/_matrix/key/v2/server 
 
 
 macaroon_secret_key 
 
 
 
 Import the Synapse database
 
 Create a new database per the Synapse PostgreSQL documentation 
 
 Or, if your Synapse database is not empty, empty it 
 WARNING - THIS WILL IMMEDIATELY AND IRRECOVERABLY DELETE DATA, PLEASE TAKE CARE. WE ACCEPT NO RESPONSIBILITY IF YOU DELETE THE WRONG DATABASE OR DATA 
Connect to the database with psql , then run the following queries:
 DO $$ DECLARE
r RECORD;
BEGIN
 FOR r IN (SELECT tablename FROM pg_tables WHERE schemaname = current_schema()) LOOP
 EXECUTE 'DROP TABLE ' || quote_ident(r.tablename) || ' CASCADE';
 END LOOP;
END $$;

DROP sequence cache_invalidation_stream_seq;
DROP sequence state_group_id_seq;
DROP sequence user_id_seq;
DROP sequence account_data_sequence;
DROP sequence application_services_txn_id_seq;
DROP sequence device_inbox_sequence;
DROP sequence device_lists_sequence;
DROP sequence e2e_cross_signing_keys_sequence;
DROP sequence event_auth_chain_id;
DROP sequence events_backfill_stream_seq;
DROP sequence events_stream_seq;
DROP sequence presence_stream_sequence;
DROP sequence push_rules_stream_sequence;
DROP sequence pushers_sequence;
DROP sequence receipts_sequence;
DROP sequence un_partial_stated_event_stream_sequence;
DROP sequence un_partial_stated_room_stream_sequence;
 
Enter the command \d and make sure no tables or sequences remain. 
Disconnect from the database 
 Extract the database dump
 unzip emsHostname-synapse-database.zip
 
 
 Import the database dump
 pg_restore \
 --username USERNAME \
 --host HOSTNAME \
 --dbname DATABASE_NAME \
 --no-owner \
 /path/to/id-emsHostname-synapse-database.dir/
 
 
 Verify that sequence was set correctly. Connect to the database and run the query
 SELECT * FROM state_group_id_seq;
 
 last_value should be greater than 1 
 
 
 Import media into matrix-media-repo according to documentation here or import media into Synapses built-in media repository using the import_to_synapse executable available from the latest matrix-media-repo release 
 
 Start Synapse and ensure everything is working as expected 
 Optionally, install Element Web or use another Matrix client 
 
 Optionally, install the sliding-sync proxy . This is required for Element X
 
 Note, we do not provide an export of the Sliding Sync database as this would not provide any value. As you need to log out and back in from Element X after the migration and in doing so your Sliding Sync proxy needs to re-sync each user. All your data is already included in the Synapse database 
 
 
 
 If you have any bridges, please see the documentation for each bridge 
 Discord |
 Hookshot |
 IRC |
 Signal |
 Slack |
 Telegram |
 Whatsapp 
 
 The process for importing the bridge databases is the same as with Synapse 
 
 
 Cancel your EMS server. See this FAQ document for instructions. Note, this cannot be undone and all your data will be lost. Ensure your imported server is working as expected before doing this

Migrate From Self-Hosted to EMS
Notes 
 Before starting with this guide, please contact EMS support from https://ems.element.io/support or by emailing ems-support@element.io 
 
 Except where specified, you should be able to just copy-paste each command in succession. 
 Please do not change any file names anywhere. 
 
 Preparation 
 This section outlines what you should do ahead of the migration in order to ensure the migration goes as quickly as possible and without issues. 
 
 At the latest 48 hours before your migration is scheduled, set the TTL on any DNS records that need to be updated to the lowest allowed value. 
 Upgrade your Synapse to the same version as EMS is running. Generally this will be the latest stable release. https://element.ems.host/_matrix/federation/v1/version is a good indicator, but confirm version with your EMS contact.
 
 This is not required, but if your Synapse version is not the same as the EMS version, your migration will take longer. 
 
 
 Check the size of your database and report to your EMS contact:
 
 PostgreSQL: Connect to your database and issue the command \l+ 
 
 SQLite: ls -lah /path/to/homeserver.db 
 
 
 
 Check the size of your media repository and report to your EMS contact.
 
 Synapse Media Store: du -hs /path/to/synapse/media_store/ 
 
 Matrix Media Repo: https://github.com/turt2live/matrix-media-repo/blob/master/docs/admin.md#per-server-usage 
 
 
 
 If you are using SQLite instead of PostgreSQL, you should port your database to PostgreSQL by following this guide before dumping your database and sending to your EMS contact.
 
 This step is not required, but will speed up your migration. 
 
 
 
 SSH to your matrix server 
 You might want to run everything in a tmux or a screen session to avoid disruption in case of a lost SSH connection. 
 Generate password for gpg encryption 
 pwgen -s 64 1
 
 Alternatively, you can use our GPG key. Note, this expires on 2023-04-28, if this is soon, please talk to your EMS contact. 
 ems-support-public.pgp 
 GPG 
 If gpg is being uncooperative, use the command gpgconf --kill gpg-agent . 
 Create a folder to store everything 
 mkdir -p /tmp/synapse_export
cd /tmp/synapse_export
 
 The guide from here on assumes your current working directory is /tmp/synapse_export . 
 Set restrictive permissions on the folder 
 If you are working as root: (otherwise set restrictive permissions as needed): 
 chmod 000 /tmp/synapse_export
 
 Copy Synapse config 
 Copy the following files and send to EMS Support: 
 
 Your Synapse configuration file (usually homeserver.yaml ) 
 Your message signing key.
 
 This is stored in a separate file. See the Synapse config file for the path. The variable is signing_key_path https://element-hq.github.io/synapse/latest/usage/configuration/config_documentation.html#signing_key_path 
 
 
 
 
 Stop Synapse 
 DO NOT START IT AGAIN AFTER THIS 
Doing so can cause issues with federation and inconsistent data for your users. 
 While you wait for the database to export or files to transfer, you should edit or create the well-known files and DNS records to point to your EMS host. This can take a while to update so should be done as soon as possible in order to ensure your server will function properly when the migration is complete. 
 Database export 
 PostgreSQL 
 Dump, compress and encrypt 
 Replace: 
 
 
 <dbhost> (ip or fqdn for your database server) 
 
 <dbusername> (username for your synapse database) 
 
 <dbname> (the name of the database for synapse) 
 
 pg_dump -O -h <dbhost> -U <dbusername> -d <dbname> | gzip > customer_db_export.sql.gz
gpg --symmetric --no-symkey-cache customer_db_export.sql.gz
rm customer_db_export.sql.gz
 
 If required, split into smaller files 
 Please only do this if you have a slow connection and are worried about transferring a single large file. 
 split -b 100m customer_db_export.sql.gz.gpg customer_db_export.sql.gz.gpg.part-
rm customer_db_export.sql.gz.gpg
 
 SQLIte 
 Compress and encrypt 
 tar -zcvf homeserver.db.tar.gz /path/to/homeserver.db
gpg --symmetric --no-symkey-cache homeserver.db.tar.gz
rm homeserver.db.tar.gz
 
 If required, split into smaller files 
 Please only do this if you have a slow connection and are worried about transferring a single large file. 
 split -b 100m homeserver.db.tar.gz homeserver.db.tar.gz.part-
rm homeserver.db.tar.gz
 
 Media export 
 If you are using SQLIte as database 
 Skip ahead to and follow Backup media export . 
 Download the export tool 
 Download the latest version of export_synapse_for_import-linux-x64 (or export_synapse_for_import-win-x64.exe ) from https://github.com/turt2live/matrix-media-repo/releases 
 wget https://github.com/turt2live/matrix-media-repo/releases/download/vx.x.x/export_synapse_for_import-linux-x64
chmod +x export_synapse_for_import-linux-x64
 
 Run the export 
 Replace: 
 
 
 <dbhost> (ip or fqdn for your database server) 
 
 <dbname> (the name of the database for synapse) 
 
 <dbusername> (username for your synapse database) 
 
 /path/to/synapse/media_store (the path to where synapse stores your media) 
 
 <yourdomain.tld> (the domain for your server. this is the part that is in your usernames) 
 
 ./export_synapse_for_import-linux-x64 -h
./export_synapse_for_import-linux-x64 -dbHost <dbhost> -dbPort 5432 -dbName <dbname> -dbUsername <dbusername> -mediaDirectory /path/to/synapse/media_store -serverName <yourdomain.tld> -destination ./customer_media_export
mv logs customer_media_export
mv media-repo.yaml customer_media_export
rm export_synapse_for_import-linux-x64
 
 Compress and encrypt 
 tar -zcvf customer_media_export.tar.gz customer_media_export
gpg --symmetric --no-symkey-cache customer_media_export.tar.gz
rm customer_media_export.tar.gz
rm -r customer_media_export
 
 If required, split into smaller files 
 Please only do this if you have a slow connection and are worried about transferring a single large file. 
 split -b 100m customer_media_export.tar.gz.gpg customer_media_export.tar.gz.gpg.part-
rm customer_media_export.tar.gz.gpg
 
 Backup media export 
 Compress and encrypt 
 Replace * /path/to/synapse/media_store (the path to where synapse stores your media) 
 tar -zcvf customer_backup_media_export.tar.gz /path/to/synapse/media_store
gpg --symmetric --no-symkey-cache customer_backup_media_export.tar.gz
rm customer_backup_media_export.tar.gz
 
 If required, split into smaller files 
 Please only do this if you have a slow connection and are worried about transferring a single large file. 
 split -b 100m customer_backup_media_export.tar.gz.gpg customer_backup_media_export.tar.gz.gpg.part-
rm customer_backup_media_export.tar.gz.gpg
 
 Transfer 
 Download the files, then upload to the Google Drive folder shared by EMS or a location as agreed with your EMS contact. 
 On your local computer: 
 scp -r -P 1234 -i ~/.ssh/matrix-server youruser@1.2.3.4:/tmp/synapse_export /some/local/folder
 
 Cleanup 
 We strongly recommend that you leave the export and Synapse untouched until the import is finished and everything is verified working. 
 Note on users and Element 
 Element does have support for changing the delegated homeserver URL. All your users will have to sign out and sign in again to Element. You should ensure everyone has Key Backup configured and working. 
 Your users will not be able to decrypt messages send in their encrypted rooms while your server is offline for the migration. 
 Force logout of old sessions after migration 
 If you do not log out all sessions for your users before the migration, you can force this later. Below is a sample config file for nginx that tells all clients trying to connect to it to sign out. 
 Note that the headers are important, otherwise this will not work one one or more of the Element clients. Valid HTTPS is required. 
 This is not tested on any other Matrix clients, but it should work in theory if the client follows the Matrix Spec.
