Exchange 2010 SP1 in production now. I get two versions of the steps needed to prepare for SP2. From different consultants. Version 1). update the schema and then apply SP2 onto server roles Version 2). update the schema and then you must also update Legacy Exchange permissions and update all Domains before applying SP2. So is Version 1 really all that's requried? setup /ps then apply SP2 onto server roles.Messaging
