Same thing stated at WES as well...sp2 gets you R2, I think you can run but not officially supported, much like the SQL clustering, can run but not officially supported yet.....
And yes, the new can be 2003, we are currently in the same boat, exchange 2003 and BES 4.1.6, have a new environment with 5.0.1 on separate environment using BES Transporter to migrate, our biggest obstacle we are dealing with now is the named property limits within exchange 2003 being reached and causing migration issues for certain users.

I called two weeks ago, and was told that R2 support wouldn't be coming until 5.0 sp2. Thanks. Regards, Michael B.

Upgrades are rarely clean or pretty. Open a case with RIM prior to starting, it will help mitigate down time. HTH John W.

I have *no* experience with BES so I need to familiarize myself with it first and go from there. Lots to learn! Just wondering if anyone is familiar with useful lists or forums? Is the process straightforward or complex? If there's anything at all that you'd be willing to share to get me started, it would be greatly appreciated!
