migrate data from StoreOnce 5100 to StoreOnce 5260

Hello Everyone,

I’m planning to migrate data from an old HPE StoreOnce 5100 to a new StoreOnce 5260.

We are currently using Veeam with Catalyst Stores, and I am still quite new to working with StoreOnce systems. I want to make sure the migration is done properly while keeping data safe and minimizing downtime.

Hi,

you can use the Veeam Scale-Out to Migrate, it is supported by Veeam and StoreOnce:

1. Create a Scale-out Backup Repository (SOBR) based on 2 extents:

Old repository (source).
New StoreOnce (destination).

2. Select the Old repository, set “Maintenance mode”, and click on “Evacuate backup” :

Veeam will start Multiple concurrent “move” tasks.
Set a reasonable “Concurrent task limit” on the destination.

3. Migration completed!

Remove old storage from the SOBR.
At the end, you have a SOBR with one extent only.
