Just a little feedback...
The upgrade worked just fine. Everything worked except as i started the upgrade i had to disable a service wich name i forgott.
I'm waiting for Exchange 2010 with the new clustering features. Hope the installation went good for the most of you who have clustered setups of ex07...
Datev can be so frustrating...i now have to move a server to another machine...and it's aweful that you have to worry about a million things wich you can only know about if you talked with the support...
the whole thing wouldn't be such a problem if you simply could setup the whole thing upon a virtualization...
my feelings during this process are bouncing between tiredness to aggression to frustation...kind of sad...
