What is the minimum Exchange 5.5 service pack that is required?
fact
Exchange Migrator 1.x

fix
Exchange Migrator supports Microsoft Exchange 5.5 SP3 through SP4. The Exchange 5.5 schema changed between Service Pack 3 and Service Pack 4. Migrating some properties from an Exchange 5.5 server running SP3 to an Exchange 5.5 server running SP4 can result in some properties not being updated correctly. If you are migrating from Exchange 5.5 to another Exchange 5.5 organization or site, be sure to apply the same service pack level to all source and target servers in the migration. The console machine running Exchange Migrator should have the same Exchange service pack level as the Exchange 5.5 servers involved in the migration.
