Really disappointed to have just found out that an in-place upgrade is not available when migrating from Exchange 2007 to 2010.
Totally understand why this is the case though. Database schema changes and the lack of storage groups in 2010 being the root cause. Not great news for the smaller places which probably haven’t got the finances to purchase a new server for a bare metal installation, or enough hardware to perform some sort of swing installation.
At least on a plus point, SharePoint 2010 does support an in-place upgrade from SharePoint Server 2007 SP2. At least one of the upgrades will be simple this year. Looking forward to trying out the new features. Shortly going to be getting our development system up and running ready to formulate our deployment plans.
Anyway, enough of my drivel. Back to coming up with a plan for our Exchange 2010 upgrade.
