Migrating from Ex2003 to Ex2007 with an existing BES install
I'm migrating from Exchange 2003 to 2007, BES v4 SP3 is already installed and working. ESM is installed already on the BES server and I've permissioned the Ex2007 server for the BES service account.
Is it worth completing the migration to Ex 2007 first and then uninstalling the Ex management console and installing the stand alone MAPI/CDO package from MS? The current version of MAPI on the BES box dates back to Exchange 2000 (doesn't look like it ever got updated when 2003 was put in)
I have one guinea pig who has already been moved over to the new server and the BES device works fine (despite a lot of errors I'm seeing in the event log).
