I have moved your post to a more relevant forum.
I would rather use the mirror method as described in these TNs:
How to use mirroring to migrate data from an old storage array to a new arrayhttp://www.veritas.com/docs/000080844
How to migrate or move storage from one array to another or change the RAID levelhttp://www.veritas.com/docs/000089031

Thanks&nbsp;MarianneI have done migration on vxvm using vxevac/mirror but here my concern is on the replication (rvg/rlink) part.Whether I need to pause/stop replication before starting storage migration and DCM log recreation is required or not.?&nbsp;Both the site I want to perform the migration one after one. (replication need to stop or not )This RVG are configured in Global cluster , I want to do this activity without downtime. It should not affect the service group.Please help me on providing steps on VVR part.&nbsp;
