We have three domestic BlackBerry domains in two datacenters (one of the domains was moved from a regional datacenter to a local datacenter during our Exchange consolidation). For one of the domains (1,100 users), we'll be performing an in-place upgrade (the hardware is brand new and there is currently no VM environment in this location). For the other two domains (4,000 users total), we'll be building up a new, parallel environment and using ET to move the users over (collapsing two domains into one). We also have an international BES server that will be collapsing into that one as well.

So far, for our major site that will use ET, I have plans of consolidating our current 9 BlackBerry servers into 4 total BES servers (basically doubling capacity on each), implementing 2-3 BAS servers, and setting up HA for the BES environment. With the exception of the DB servers, all of these will be virtual machines. We'll end up moving from 20 servers (BES and DB w/ live DR) to 13 servers (BES and DB w/ live HA). The only downside is that, due to the warm-standby model of the HA configuration, the active OS licensing required will increase from 10 licenses to 12 licenses (SQL standby can remain in a DR licensing scheme, to my knowledge).
