  • Method and system for non-disruptive migration
    Patent number: 8812806
    Abstract: Method and system for migrating a virtual storage system from a source storage system having access to a source storage device to a destination storage system having access to a destination storage device is provided. A processor executable management application estimates a likelihood of success for a migration operation before the migration operation enters a cut-over duration during which client access to the source storage system and the destination storage system is restricted. The migration operation enters the cut-over duration if there is high likelihood of success for completing the migration during the cut-over duration or aborted, if there is a low likelihood of success for completing the migration during the cut-over duration.
