Migrating From Data Domain To NBU Appliances

[Georges_Achkar]

Hi,

One of our customers is currently using NBU 7.5 for two infrastrucutres (Unix and Windows). Recently they decided to move to NBU Appliances (5230, 3 of them). 

what is the easiest way to migrate the existing data from the DD appliance to the new NBU appliances? are there any considerations for the NBU?

A reasonable solution would be to leave the old data on the old DD and let it expire naturally with time and push new backups to the NBU appliances. But again this is a time consuming process. Is there any other way?

Regards,

Georges

You could duplicate the images over, but that as well could be a very time consuming process with rehidration and then deduping the data again on the appliance. 
 

It might be best to let them expire on the DD and just write new images to the new diskpool.

The answer to the question relies on the retention period for those images on the DD.  As SymTerry says, the images can be duplicated from the DD to the 5230 with bpduplicate, but if you're only dealing with a 30 day retention, I'm not sure I'd bother with it at all.

If these are long-term retention objects, setting up duplicate jobs isn't that hard, and if both systems are on the same 10GbE segment, you should see decent performance even with the rehydration needed.  The 5230 should be able to ingest the data at a rate faster than the DD can present it in most cases.
