How to Duplicate One FS PBX to Another but maintain separate Domain Names?

I want to copy one FS PBX system on a cloud VM to another FSPBX system on another Cloud VM. The domain names would need to remain different as would the IP's. Is there a guide describing how to accomplish this? I want all the default parameters from the old system moved to the new system, along with recordings, voicemail greetings, etc.

I absolutely agree but I have found no good documentation on how to restore that database. There is another thread in here where someone made a script to do the work but it did not work when I was trying to copy from Debian-12 to Debian-13. There simply isn't enough documentation on the internals for this. Other things like extracting a particular domain to move to a different server would also be good.

I'm assuming it isn't as easy as an untar of the backup files.

Well, I re-imaged my cloud VM, re-installed FS PBX, the followed the script on this thread: https://www.pbxforums.com/threads/backup-restore.8702/#post-35209

It worked and restored the original FS PBX configuration to the new host. I changed the domain name, rebooted, and all is OK so far.
