EnglishHi,
Wanted to check with anyone who has already upgraded the OS on a Mailcow system to see if there are any issues or if it can be run without any nasty surprises?
Have 3 systems happily chugging away on 18.04 but would like to upgrade at some point soon..
Cheers
Rup
I had no issues upgrading from 18 to 20 and from 20 to 22. I can’t speak for 18 to 22, but in general there shouldn’t be issues upgrading the OS.
Have something to say?

As part of me trying to get experience with mailcow i setup a local vm on my laptop with ubuntu 20.04 lts , restored a backup of a test mailcow and then after making a snapshot ( i know it’s test but also handy to hop back and forth for some testing) upgraded to 22.04 .. worked without a hitch.
Depending on the size of your cow, i find the mechanism for backup and restore or cold_standby so easy , that if you have some resources on a spare system you can always do a testrun and see what it does..
