Abstract
Methods and systems for Vserver migration are provided. One method includes executing a transfer phase of a migrate operation for migrating a Vserver of a source cluster to a destination cluster, using asynchronous baseline transfer to transfer a plurality of source storage volumes configured in a consistency group (CG) for the migrate operation to a plurality of destination storage volumes of a destination cluster; updating a state of each of the plurality of source storage volumes to a sync state indicating completion of a pre-commit phase of the migrate operation to initiate a commit phase of the migrate operation; and generating a snapshot of the plurality of destination storage volumes for performing data integrity checks between data stored at the source cluster and migrated data at destination cluster, after completing a commit phase of the migrate operation.
