I haven't considered that as there is no identical server available, at
least not easily. But you said something very interesting: Take any MCS-
equivalent server that supports running both versions. If that really
is sufficient (I don't think I need working licenses just to perform
the DRS backup, and even if, the MAC could be - ahem - tinkered with
in the isolated network), that would ease things considerably.

I'll see if any supported server is available. There's quite a chance
of that, and as you said, it would make the transition even less risky
(human error during the initial steps in my procedure could still wipe
the original pub blank).

Thanks,
Andre.
