Upgrading domain to 2008 R2 while EV 8 sp1 is on 2003
We have Enterprise Vault Server 8 sp1 installed on a Windows server 2003 R2 sp2.
Our domain servers also are installed on Windows servers 2003 R2 sp2 and functional level is mixed mode.
I plan to migrate the domain to 2008 R2 (x64)
Is it possible for now to let EVS untouched on windows 2003 member server?
Or do i have to update/upgrade/migrate EVS and the member server before?
