Reinstalling v18 with a backup from v18.0.9.23 when the downloadable ISO installer is v18.0.9.20

Hi

I assume someone have to bake a new ISO to make this possible...?



A weekend-destroyer for a poor 3cx developer who now have to work over the weekend to solve this

Reason for reinstall with restore
I have an issue with change of datacenter and the static IP address of the server is changing. No way to keep the old one.
I then, if this still applies, have to reinstall the server with the new static IP and restore the backup. Or has this been eliminated in newer versions?

I run Debian and have both old and new IP in the production server with dual NIC configuration. The old IP and NIC shall preferable be removed early next week. I assume i will ahve to reconfigure the SBC's after this.

I also got issues with provisioning of new phones. Hotdesk provisioning still works but not resetted phones. I suspect, as no one else seems to have any provisioning problems after the last V18 update, that the dual IP address has something to do with this as well.

My plan was to do a new install and restore the config to a VM with only 1 NIC that has the new static IP address and then reconfigure the SBC's.

Or am I doing this restore work in wain and the static IP address can nowadays be reconfigured and then simply reinstall the SBC's pointing to the new server IP and I'm done?

I recall the IP is not part of the backup. SBCs should be using the FQDN not an IP address.

Depending on your license type the TTL for a 3CX FQDN is 6 hours for Pro or 5 minutes for Enterprise.

Previously (v16 and older) then this was the ONLY way to change the local static IP on the server.

Is it still required to do a backup/restore to move from one local static IP of the server to another IP (10.200.8.199 will be 10.200.5.199) or is this entirely obsolete?

It almost looks like its obsolete nowadays as I can change interface in the settings but it would be good to know as it then would mean that the provisioning issue I have is not related to the dual IP address issue.

Hello you will have to install a blank 3CX with your license key, run the updates, upload your backup then restore.

Note that when you do this, it will trigger a DNS change on your FQDN (providing youre on a different network).

You will need to do a license refresh on your existing to get the DNS to go back. But if youre doing it in one go i wouldnt bother.
