I still recommend to go for a virtualized environment consisting of a Server 2008R2 Standard as Hypervisor + SBS2011, and a second instance of 2008R2 for the BES10, or Server 2012/2008R2 as Hypervisor + SBS2003 plus a second instance of 2008R2 for the BES.
Thanks for the reply. In order to het virtualization capabilities I believe I must use the essentials versions which are 1,500 dollars more than the STD versions. That's just too expensive for my 4 user environment.
The grace period is interesting
What about upgrading to one of the BES express versions. Are they supported on the newer 64bit servers? I was going to upgrade a while back but never did.
