migration from 2.0.16

[lists]

I have found opensuse to be very stable and the upgrades to be drama free IF (big if) you stick to the distribution repositories. For a server, sticking to the disty repos is very likely. It is desktop users (me) that load a lot of software from other repos that occasionally muck things up.

I run centos 7 on my servers and opensuse on the desktop. They are very similar. I always have trouble when I have to use Debian, which these days is only on a R Pi. Opensuse can use three different package managers, one of which being yum.

We own the servers and use CT (LXC).
The IBM move is clear, but going to C7 today seems to me not a good
choice.
It is in its descending stage and in a couple of years packages are going
to became very outdated.
If RH8 remain "open source" I suppose the community or some interested
medium level company that use CentOS for their business can became a new
CentOS and switch to a different named distro is supposed to be only a
question of replace repositories.
That seems to me a smoother path (IMHO).
Debian 10 is EOL on 2022
Ubuntu LTS seems a solution, but I hadn't ever used it (I may be wrong,
but in the past Canonical don't inspire me to much trust).

Other options (not too "exotic")?

I am studying the situation, but there are many variables and the old age
of the source server probably meke it more complex.
And I am not a dovecot expert ...
