Deduplication Store Size

I need a solution

Hi

I am actually using a disk array to provide a 12,5 TB disk to my backup exex 2012 server.

This space is used as a deduplication volume.

 

I need to extend size of this volume. I bought a few more disks to increase size up to 17,5 TB but I encounter the following problem.

Block size of my Windows Volume is 4096 and so I would not be able to go higher than 16 TB for volume size.

 

How could I change block size ? I heard that the only way is to format partition (and thereby losing all my backup data)

If this is mandatory, how could I transfer all data to another storage location and get it back for BackupExec to use again after transfer on new location?
