Migrate data from Cellera to Data Domain

We have setup a SourceOne environment where all the data is located on EMC Cellera storage device.

We want to move away from EMC Cellera and migrate all data to EMC Data Domain.

In SourceOne we are able to configure two 'backend archives' and we can manually initiate a copy of all data from EMC Cellera to EMC Data Domain.

Since this is a lot of manual work, I was wondering if it is possible to migrate this with a tool (EMC PS?) direclty to EMC Data Domain

Even a copy is just enough for us.
