A (privileged) container or a VM will do the trick.

Not really, it is supposed to work.

However, with an in-place package upgrade the rollback is much more work 
than with a separate machine.

Another advantage is that for a separate machine only the protocol on 
the wire has to be compatible to succeed, whereas with a package upgrade 
you are talking about lots of local files and databases.
