Hmm, maybe the Sunday is a mistake with the time zone difference. This
would mean I'd only start at 17:00 (CET/UTC+0100)[1], this is pretty late.

How early is the NOC staff on Saturday, and are you willing to start
Saturday? Migrating services means the upgrade will take longer and we'd
need an OS install every now and then (not all in one go).

I've made a rough overview at:

I am not sure about moving the menubar and container services. Container
has a very large storage. With 100+GB used, I am not sure where to move
that to. Menubar with the mailman stuff is IMO very difficult to move.
I'd rather have a mail backlog.

If you reinstall the OS, will that be a wipe and reinstall (ouch) or an
upgrade? I'd prefer the latter.
