Mass recall from IBM DR550

Hi experts,

I have an evironment with EV 9.0.2 that will updated soon to 10.0.4. At first or maybe after the updated we will change the DR550 HSM hardware to a EMC Centera. For this we have to export or move the data to the new machine. My idear is to restore the data (0,5 TB) back into the first EV store and migrate that data into the new device then.

Is it possible to recall all CAB files with EV tools back into the first EV store?  

And if not, is it possible to use the Tivoli Storage Manager Client to restore all the data out of  the DR550 into the original EV partition without data lacks? 

Best regards

Gerd
