I am pretty new to the Centera and DiskXtender. I am trying to get completly off the Centera so it can be decommisioned. We have a couple of file servers that have DiskXtended drives on them. What is the easiest and cleanest way to migrate off of the extended drives? Is there a way to tell how much data is on the extended drives so i can make sure i have the available space to migrate them?
