About to install BES 5.0 and have a SQL 2008 install that I can point it to. It looks like RIM doesn't officially support SQL 2008, only 2005, so am wondering if any server fault peeps have it running and if there are any hiccups.
Are you going to install it on a production server? I don't have SQL2 2008 to test it, but if RIM doesn't support it I wouldn't install it on a production server.
It might not be the best option, but I think BES 5.0 comes with the ability to install to MSDE if you don't have SQL 2005 running somewhere.
EDIT: Several users on RIM's support boards are reporting that BES 5.0 doesn't even recognize SQL is installed if you are running SQL 2008.
TSupport says BES 5 (MR1 only v5.0.1) is supported on SQL 2008 x64 or Express with SP1.
They are having issues with SQL 2008 on Windows SBS 2008.
I've got BES 4 installed against a remote SQL 2008 instance and it's working fine. I can't imagine that BES 5 wouldn't work. On a local instance it might be different as the server will look for services which may be named differently.
You may need to tell it that it's a remote database instance, but give it the local connection information.
So I'm answering my own question.
BES 5.0 against a remote SQL 2008 instance works like a champ. I didn't try a local instance.
Full config is; BES 5.0 installed to Server 2008 x64. SQL Server 2008 x64 on Server 2008 x64. (all Hyper-V slices as well)
Have about 40 low use users and about 4 high use users.
If I run into anything down the road, I'll edit the answer.
Absolutely no hiccups at all as of March 23, 2010.
