OK, so the idea of having BOTH 5.0.16 AND 6.0.1 running together on the SAME server, production, seams quite far fetched... should I even ask if it's possible? LOL
So, would it be possible to have two servers, one 5.0.16 and the other 6.0.1, running together in the same network? ...with the same mail.domain.com? How would that work?
If this was possible could I then setup a portal page where the user could choose what version to use? ...then redirect them to the version server?
But this would create a backup nightmare, huh? ...I don't even want to think about it....LOL
Then eventually, when everyone moved to 6.0.1, would there be a way to export user settings, calendars, emails, ect from the 5.0.16 to the 6.0.1 server?
Mind you this is ONLY for ~35 accounts....
LOL...crazy ideas...can't wait for an answer...
