How to expand the 4 drives from each 1.5Tb to 4Tb?


I want to update my EX4. Now I have 4 x 1.5Tb drives, and want to change each to 4Tb (4 x 4Tb).

Can I change every 2 days a week one drive, and then change the partition?

I am looking for the fastest, easyiest way.

best regards



it’s not a DROBO and doesn’t support that I don’t think 

Manually backup your data, add in the new drives re-configure the arrarys and restore your data.
