3CX V18 EOL - How to recover customer platform?

[adconsulting]

Hello,
We have a problem with some of our customer PBX.
We were not able to update them before the 30 of march and now the licenses are expired and we cannot upgrade the platform.
It's impossible for us to re-create a new domain and re-provision everything. Is it possible to re-activete the license with a PRO one in order to force the v18 to v20 upgrade?

It's very important for our customers.
Best regards
Davide

Are they Linux? If so, you can try an "apt update && apt upgrade 3cxpbx -y"

Otherwise, you're pretty much screwed. There's no installer for v18 latest build that can activate. It was only available for active installs.

cannot upgrade

You should still be able to install v20 and restore a backup.

The v18 ".35" update to maintain activation was released in mid January give or take.
