Upgrade from V18 Build 4 Role Not Available

[Avram Grossman]

I'm trying to upgrade from V18 Build 4, however I cannot assign an extension to the role of System Administrator.
Right Role only shows Manager, User, Receptionist.
I tried to update to V18 Build 5 final but it say my "support" has expired.

What is the next best way to get the V20 upgraded installation?
This is for an on-premise installation 4 extension system.
Thanks,

Before you can upgrade to V20, you have to get your 3CX upgraded to V18 SP9. That's not going to be fun, if it is even possible. It sounds like you have a very small system. Perhaps the best way forward is to keep your existing system in place and functional while you setup an entirely new 3CX server and install V20 from scratch. If your 3CX only has a few extensions, trunks, and contacts, I would just manually reenter the settings into the new server. I like starting from a fresh server rather than multiple in-place upgrades.

Interesting. That is what I had to do with another outdated 'small" system. Sounds like the easiest path. Thank you for the suggestion / reminder.
