Hi folks,

Is there a procedure on how to upgrade hard drives in EX2 that are set up as Raid 1. Currently have 2x 2TB drives, would like to upgrade to 2x 4TB drives.

Thanks

The following guide explains how to properly replace both internal hard drive units in order to expand the maximum capacity:

Replacing an internal drive on a My Cloud Mirror, EX2, or EX4 device

However, I am not aware if you are able to mix an original hard drive with a larger hard drive, rebuild, replace the remaining unit, and rebuild again in order to migrate. I would recommend contact WD Support about this.
