License v18-v20

[JohanFer]

Hi
I am planning a upgrade from v18 t v20 on my largest system (2000 extensions) on Windows server.

My question is if my upgrade fail during v20, will my license still work when falling back to v18:

Regards
Johan

No, once a license has been upgraded it will not be able to be downgraded.

With a Windows server you shouldnt have an issue. Just ensure you have followed the 3CX checklist document https://www.3cx.com/blog/releases/v20-upgrade-checklist-faq/
