[Samba] Planning the move to 4.12

[Stefan G. Weichinger]

As some of you may know I run some AD-sites with Samba DCs and DMs.

Currently I use the "maintenance mode" release 4.11.11 (packages from
Louis ...) and things work fine.

My question:

Is it recommended to move on to 4.12.x and if yes, why and when?

We don't lack any features afaik, but I understand that someday 4.11.x
will not be maintained anymore.

No hurry, I just want to learn how to approach that.

And for sure I'd like to know if there are specific things to know or
steps to follow.

DCs first? DMs first?

Maybe this also helps other samba-admins, thanks.
