Swapping HDD drives for new and copying data

Hey guys need a bit of assistance.

I have a Gen 2 Mycloud Mirror 4TB which I have set to Raid 1.

I am now only left with just under 1TB as I have stored my films, photos etc.

What is the easiest way to copy all the current data to brand new HDD? For example I want to buy 2 x 4TB or 8TB drives and have them set at Raid 1 again.

How do I copy across all my data from the existing HDD to new ones? I am mainly using the my cloud mirror as a plex server

Thanks!

Hello,

Since the unit is on a RAID configuration, you might need to copy the files to a different device and then transfer the files back to the new drives on the unit.
