Changing FQDN of an existing 3cx Phone System

[dsaplbg]

Hello,

can i change existing FQDN of an system. And register an existing licens to the new FQDN?

You need to backup without license and FQDN.

Then, release the FQDN from the Keys page on your Customer Portal.

Restore the backup, re-enter the same key and choose a new FQDN during setup.

Note that all phones and SBCs will not work until you reconfigure them for the new FQDN.

Do note that there is no guarantee your original FQDN, once released, will be available.
