Take a look at the BES4 installation guide. There it says that you need at least a BES 3.6 with SP3 before you can upgrade.
Yeah, I caught that last night after I posted. I upgraded to SP3, installed MDAC 2.8, and then upgraded to 4.0. I just had the installation upgrade the existing database and everything seems to be working fine. I saw a few errors in the Application Log of Windows Event Viewer - one was caused by an old service from 3.6 that no longer exists in 4.0(User Admin or something like that). I called TSupport and they just had me delete the relevant registry key. I am getting a few Application Log warnings for individual users, but for the most part it went pretty well, and even the users who are generating errors seem to be receiving mail so I guess we'll see...
