Identify a D2D appliance to act as replication target for temporary storage of the data to be migrated. Ideally for best performance the replication target appliance should be co-located on the same LAN as the original D2D. 2. Upgrade the firmware on both D2D devices to 2.1.00/1.1.00. 3. Ensure that the D2D to be used as replication target is licensed for replication. 4. Configure a replication mapping using the Replication wizard on the original D2D to allow replication of all data from the source device to the new target device. See the D2D user guide for detailed steps to create a replication mapping for NAS or VTL. 5. Allow replication to complete so that both stores are synchronized, this will take some time as the new share/library is a separate deduplication store so all data needs to be replicated. 2 Step 2 - Delete original VTL/D2D share and create new one 1. Stop any backup jobs from running to the source device so that both source and target now remain identical. 2. Remove the replication mapping from either the source or target D2D Web Management Interface 3. Delete the device on the original D2D appliance. 4. Create a new device on the original D2D appliance. If using NAS (CIFS or NFS) ensure that you give this share the same share name as the original share as this will ease the migration of the backup application devices. 117

Step 1
Replicate data for migration
1.
Identify a D2D appliance to act as replication target for temporary storage of the data to be migrated. Ideally
for best performance the replication target appliance should be co-located on the same LAN as the original
D2D.
2.
Upgrade the firmware on both D2D devices to 2.1.00/1.1.00.
3.
Ensure that the D2D to be used as replication target is licensed for replication.
4.
Configure a replication mapping using the Replication wizard on the original D2D to allow replication of all
data from the source device to the new target device.
See the D2D user guide for detailed steps to create a replication mapping for NAS or VTL.
5.
Allow replication to complete so that both stores are synchronized, this will take some time as the new
share/library is a separate deduplication store so all data needs to be replicated.
Step 2
Delete original VTL/D2D share and create new one
1.
Stop any backup jobs from running to the source device so that both source and target now remain identical.
2.
Remove the replication mapping from either the source or target D2D Web Management Interface
3.
Delete the device on the original D2D appliance.
4.
Create a new device on the original D2D appliance. If using NAS (CIFS or NFS) ensure that you give this
share the same share name
as the original share as this will ease the migration of the backup application
devices.
