Hello, I have migrated 3cx server from 1 google cloud account to another. First 3cx server was trial, and new one is with pro license. I have successfully restored backup to new 3cx installation, using new FQDN and license.
Now I need to do the following:
1. Connect SBC to new 3CX
* Tunnel password
* FQDN of new server
* PBXSipIP: Local IP of the PBX
2. Change option 66 under DHCP with new provisioning link from new 3cx server
3. Shutdown old server, and enable trunk on new one.

When I do this, do I need to factory restart phones, or it's enough to reboot them and let them grab new provisioning URL from DHCP?

Thanks in advance!
Regards.
 
Strongly recommend factory reset.
