Hello Wanderlei and Patti,
I think that the migration jobs were designed to accomplish this also. You can configure a migration job to migrate all your volumes from a pool (associated to your old storage device) to another one (associated to your new storage device).
Also, if dealing with disk volumes, you can configure your new storage identical to the old one (name, archive device, media type, etc.), move your volumes to the new device (filesystem mountpoint), and then remove the old storage filesystem mountpoint.
Best regards,
Ana
