ABSTRACT:
A method and system for performing a failover process on a production server. A source server and disaster recovery server are assigned indicators when operating in failover mode. A version match is performed to validate that the Exchange server applications and the storage area network vendor resources are compatible for the source and disaster recovery servers. Thereafter, multiple mailbox stores are dismounted on the source mailbox server. In turn, multiple databases and multiple transaction log drives are dismounted. After this step, drives are mounted in the disaster recovery location that are mirrors of the source server database and transaction log drives. After mounting, an Exchange System Attendant resource is created or Exchange and user attributes are updated in Active Directory. Finally, Exchange services are started and mailbox stores are mounted on the disaster recovery server.
