Default Re: BES5 to 10 in a small environment, frustrations...

BES 5.0.X should run concurrently with the 10.1.x Server on one machine.
However, there is additional pain to upgrade your BES 4.x to 5.X. Also, There is no in place upgrade path from BES 4 to BES express 5.
If you want to run everything on one server, then use the microsoft migration toolkit and the 21 days grace period. After that decomission the old SBS2003 and the BES 4.X.

I am a small business guy as you. My BES installations are from 1 to 10 users. I think virtualization makes many thing easier, regardless if your are running a small or a big shop. If problems occur, they only affect one instance if you have virtualized a server, not everyhting. But, of course its your very own decision.
