how to change a fqdn

[uniscanadmin]

I updated the system from version 18 to 20. together with reinstalling debian. When restoring from a backup, the system itself gave me its own vision of my new URL. How do I set my own values fqdn?

Restoring from backup on v20 restores the FQDN and license key. If you are using a 3CX FQDN then it will update...Pro licenses have a 6 hour TTL, Enterprise licenses are 5 minutes. Does that answer your question?

My question is: how to change the full domain name of PBX from 3cxmsk.my3cx.ru to mydomain.com?

Reinstall with own FQDN and certificate: https://www.3cx.com/docs/fqdn-ssl-certificate/

@uniscanadmin In v20 per 3CX you'll need to start over as @bitn2 suggested.

You need to start from scratch, like a new PBX.
