Following are requirements for redirecting Exchange 2000/2003/2007/2010 storage group and database restores:

• The storage groups and databases must already exist on the target server, and must have the same names as the original storage groups or databases.

• The destination server must have the same Organization and Administrative Group name as the source server.

• The destination databases must be configured so that they can be overwritten.

  See Configuring a database in Exchange.

You cannot redirect the restore of the following:

• A version of Exchange server database to a different version of the database. Service packs for both Exchange servers should also be the same.

• Site Replication Service (SRS) and Key Management Service (KMS). These services are dependent on the computer they reside on; redirection to another computer is not supported and could result in the loss of functionality of these services.
