Zusammenfassung:Methods and systems for Vserver migration are provided. Update after claims are finalized. One method includes generating a consistency group (CG) having a plurality of source storage volumes of a source storage virtual machine (Vserver) of a source cluster for a migrate operation to migrate the source storage volumes as a group to a plurality of destination storage volumes of a destination cluster; establishing a mirroring relationship between the source and destination cluster for managing asynchronous transfer of the source storage volumes in the CG to the destination storage volumes during a transfer phase of the migrate operation; replicating a logical interface of the source cluster to the destination cluster, the logical interface providing a network address to access the source cluster; and automatically selecting a destination port at the destination cluster, associated with the replicated logical interface.
