I want to migrate  our old SAN storage backend which contains LVMs  used for the cloud storage,  to a New SAN Storage box.

The requirement was to migrate all storage of the old SAN box, which was mounted to the controller node  as  /dev/sdb  and /dev/sdc  around total 6TB storage. 80 % full. Then AMC of this box getting over. 

So what all are the steps to  perform the migration of the old storage to new SAN storage .

Any hints most welcome
