Replacing a hard drive

I have a MyCloud ex2 ultra and currently have the 2 bays filled with a 3TB and 2TB drive configured as Raid JBOD. I fear that I am getting low on space and thought about replacing the 2TB drive with a 4TB drive but don’t really know what I have to do to do that, given that the system is set up as Raid JBOD.

Can I just remove the 2TB drive, clone it to a larger drive and then reinsert the new drive into the bay and be done with it? Or do I have to do something more complex? What, exactly, is the correct way to replace a drive with a larger drive in the Ex2 Ultra?

Thank you for the response, but what is the best way to copy the data.

The 2 disks are configured as RAID JBOD and there are 2 shares. Assuming that the existing disks are A and B and the new disk C, can I just remove A, put C in, use Finder to copy from B to C, remove B and reinstall A? Will that work? Or is there a faster way?

I could not find a copy function in the dashboard so I don’t know how else to do the copy other than using Finder and Copy-and-Paste.

OK. Thank you. I will give that a try.
