Hi Frankgfan,
Thank you for your update. Yes we are migrating storage by using mirroring only but here in VVR diskgroup, i am not sure about command syntax to be used to mirror volume which have DCM log seems to be mirror over 2 disks & I hope mirroring is fine for SRL volume as well to migrate storage. Sorry I am new to VVR.
Could you please assist me here. Below op for reference.

or
you can disassociate the existing DCM then create a new one (https://sort.veritas.com/public/documents/vis/7.1/windows/productguides/html/sf_admin/ch11s03s05s01.htm)
it is highly recommended to perform these tasks in a maintenance window meaning rlink is up-to-data and all the apps are idle (no active IOs).
- Hi,
Thank you for update. As provided link the mirroring was done through GUI. We dont have that. Could you please help me with command syntax to mirror volume db-oradev-dcdr-ora_ogg1-vol with dco log that will be great help.
you do not have to stop replication while migrating the data to a new storage.
recommend to use data mirroring instead of using vxevac (to play safe)/
please consult with the TN below in storage migration
