Thanks. This was part of a "free" (love that word) head swap which was part of an agreement with NetApp, and my disk capacity for data is absolutely not an issue - as a matter of fact I will be getting some space back later in the year as a huge project completes. So buying another shelf is 100% not on the table.
Assuming I was able to obtain "swing gear" for the migration - I could migrate all of the volumes housed on these shelves to a new aggregate, redo my aggregates, and then move everything back- correct?
