Just add the new storage and weight the old storage to 0.0 so all data will move off of the old storage to the new storage. It's not unique to migrating from SANs to Local Disks. You would do the same any time you wanted to migrate to newer servers and retire old servers. After the backfilling is done, you can just remove the old osds from the cluster and no more backfilling will happen.

Now we want to get rid of SAN storage and move over ceph to LOCAL disks. Can i add new local disks as new OSDs and remove the old osds ? or I will have to remove the ceph from scratch and install it freshly with Local disks? Regards Gaurav Goyal
