Re: Different releases in the same server

Hi Christoph,

thank you very much for your time.
We know the 2
releases are old, unfortunately we cannot change requirement,
we got
this server under our management 3 weeks ago, and customer asked to
upgrade urgently to 12.
It's a governement agency, and the limit is due
to certification matrix with application running
against the
database.

We totaly agree with you about to switch to a new VM built
from scratch, but probabiy this wont be possible,
so we need to
understand in deep what we could face in the migration step having this
server and (we hope) a clone to test on.

thanks again
regards
Marco
