| | Question re: BES 5.0.2 Install - Coexisting EX2003 & EX2010
Please Login to Remove!
We currently have mailboxes on Exchange server 2003 SP1 with their BB devices working OK on BES 4.1.
I have installed Exchange Server 2010 SP1 and I am now in the process of installing BES 5.0.2 into the environment (same AD domain and Forest).
During setup, I will be prompted to specify which Exchange Server the BES server will talk to. As my BESadmin account is still on Exchange 2003, do I point the BES server to Exchange 2003? Ideally/eventually, I will have an Exchange 2010 & BES 5.0.2 environment.. so should I choose Exchange 2010?
Am I right in assuming I have the two following options?:
1. I create a new BESadmin mailbox account (eg. BesAdmin2010) in Exchange 2010, add all the required permissions to this mailbox that BESadmin currently has, and point BES to Exchange 2010 during set up?
2. I migrate the current BESadmin mailbox to Exchange 2010 and also point BES to Exchange 2010 during set up? Will this mess with the current 100 BB active devices that are still hosted on Exchange 2003/BES 4.1?
I hope this makes sense?
Thanks in advance.
