Retaining your data via StoreOnce Replication If you are already using replication to provide an off-site copy of the data being backed up to the appliance that you are converting, this is the best way to migrate data back onto the appliance after conversion completes. If you are not currently using replication but have other HP StoreOnce appliances available, these could provide you with a way to retain your data over the conversion process. Some important points to note are: 1. Make sure that replication is complete. 2. Make sure that all data required is being replicated. Check your VTL cartridge mappings and share mappings to make sure that everything is replicated. 3. You should remove replication mappings from and to the appliance being converted before commencing the conversion process. This will ensure that the replication partner devices return to their non-replicating mode and are available for restore operations if required. 4. Remember that replication recovery to your converted appliance will take a very long time over a low bandwidth link. You may need to consider other "seeding" processes to speed up the recovery process, such as co-locating the appliances on a LAN. Retaining your data via StoreOnce Replication 11

Retaining your data via StoreOnce Replication
If you are already using replication to provide an off-site copy of the data being backed up to the
appliance that you are converting, this is the best way to migrate data back onto the appliance
after conversion completes. If you are not currently using replication but have other HP StoreOnce
appliances available, these could provide you with a way to retain your data over the conversion
process. Some important points to note are:
1.
Make sure that replication is complete.
2.
Make sure that all data required is being replicated. Check your VTL cartridge mappings and
share mappings to make sure that everything is replicated.
3.
You should remove replication mappings from and to the appliance being converted before
commencing the conversion process. This will ensure that the replication partner devices return
to their non-replicating mode and are available for restore operations if required.
4.
Remember that replication recovery to your converted appliance will take a very long time
over a low bandwidth link. You may need to consider other “seeding” processes to speed up
the recovery process, such as co-locating the appliances on a LAN.
