Descrizione

A use case for this is, say someone started with controller local as deep store, and then wants to migrate to using Azure as deep store. If they enable this, the newer segments will use Azure as deep store, but the older segments will still remain on controller local disk. The only way to move the old segments is to manually copy them over to Azure, and then modify the segment zk metadata.

An admin tool for migrating from deep store X to Y would be handy.
