Moving volume SnapMirror or qtree SnapMirror sources

About moving sources

Whether you are moving a volume SnapMirror source or qtree SnapMirror source to new storage systems or newer drives, as long as there is a Snapshot copy in common on the source and destination, the transition goes smoothly. Volume SnapMirror transfers all of the Snapshot copies as part of the SnapMirror process. Qtree SnapMirror has only one Snapshot copy in common, and different destinations will have no Snapshot copies in common; different destinations will not have Snapshot copies in common unless you replicate them.

When to move sources

In a production environment, you should perform the process of moving SnapMirror relationships from one volume or storage system to another only in a maintenance or out-of-service window. Ensure that new data is not added to the original source during the move.
