Storage Migration Steps - on VVR

Level 4

Hi ,

I want to migrate storage on VVR. Below are the steps I have in mind. Please guide me to do it in right way.

1. Stop the replication between DC1 & DR

2. Add the New array lun on primary site node.

3. Vxevac from Source lun to target lun. Same for SRL

4. Check the DCM for the Volume after the migration

5. Proceed the same on Secondary site and start replication

Below is the Diskgroup which I want to migrate.

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 array

How to migrate or move storage from one array to another or change the RAID level

How to migrate volumes to new disk enclosures using Veritas InfoScale and Storage Foundation

Thanks @Marianne

I 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.? 

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.

Can anyone help me on this VVR ?
