##################

as the old storage is out of support, i'm migrating the data to new storages. Now i have virtualized new storages to IBM SVC and mirrored the data. Assiging single mirrored LUN to exising VCS cluster node to replace Old storages.

****** i want to do plex mirring and remove old storage plexes one by one by allsites=off, siteconsistent=off. 
so that i can keep only SVC LUN in DG. 
I'm not changing DG name, keeping same. Only underlined Disks, subdisks, plexes are changing.

My Query is  :
Do i need to do any changes from VCS cluster?
Kindly suggest me .
