Updating self hosted bitwarden on Ubuntu 1804 to Ubuntu 20.04?

Hi
I have a perfectly working self hosted bitwarden on Ubuntu 18.04 and I am wondering whether anybody has updated to Ubuntu 20.04 without any issues?

I dont want to just run the Ubuntu upprade commands if it messes with bitwarden.

Has anybody done this before and are there any gotchas I need to be aware of?

cheers
