Trying to migrate my ODK deployment and its data from AWS to Digital Ocean

• Take a full machine backup of src.
• Over ssh, rsync the key folders (/var/lib/docker, /root/central) from src to dest. This might take some time.
• Start the maintenance window.
• Block all incoming HTTP/S traffic to src.
• Shutdown Central on src with docker-compose stop;
• Rsync the key folders from src to dest again to pick up the latest changes to data. This will be faster than the first rsync.
• Shutdown src and take another full machine backup.
• Only allow incoming HTTP/S traffic only from your IP to dest.
• Update the DNS record to point to the dest. This should happen quickly if your DNS TTL is low.
• Bring the dest server back up (docker-compose build; docker-compose up -d).
• Verify you can login via the Central UI to dest, see records, preview forms, etc.
• Allow all incoming HTTP/S traffic to dest.
• Stop the maintenance window.

Just to note that the above steps worked ok again for me once to migrate my Central instance to a new server. I’m still affected by Central: containers not starting after boot, do start manually with "docker compose up" even after upgrading to Central latest version after the migration. Not really sure how to fix that (other than restarting the containers after boot), I would appreciate any pointer.
