You’re absolutely right that you can migrate the drives from your DS713+ to the DS925+ — just make sure you keep the original order and do not choose “Initialize” when setting it up. The system should recognize the volume and let you continue using it without data loss.
As for the DX213, unfortunately, that expansion unit uses the older eSATA connection, which is no longer supported on newer NAS models like the DS925+. The DS925+ only supports expansion via USB-C to DX525, and older expansion units can’t be connected physically or with any workaround — even the drive-mounting hack for unsupported drives won’t help here because the connection protocol itself is incompatible.
However, you can still reuse the two drives from your DX213 inside the DS925+ itself. Here’s how:
• Simply insert the two DX213 drives into empty bays in the DS925+
• You’ll be prompted to create a new storage pool/volume with them (they won’t merge into your existing pool)
• Yes, they will appear as a second volume or pool, completely separate from your migrated DS713+ drives
• You can use that pool for general storage, backups, media, etc.
One tip — if those DX213 drives are currently in a RAID configuration (e.g., RAID 1), they won’t auto-import into the DS925+. You’ll need to recreate the pool on the DS925+ (so make sure to back up any data on them first if needed).
