Switch MyCloud HDD to MyCloud EX2 possible?

Hello Community,

I’m using a single bay My Cloud with WD Red 4 TB HDD for some years now and the free space is getting low. So I just got myself a MyCloud EX2 Ultra empty case and another WD Red 4 TB.

What I want to do is to power down my old MyCloud, detach the HDD, reatach the HDD to Slot 1 in the new EX2, attach the second new HDD to slot 2 and power up the new EX2 on the same ethernet port.

Will this work?

I suspect that parts of the firmware or settings are stored on the HDD and I’m not sure if the devices are compatible with each other that it’s that easy. The last thing I want to do, is to lose my data or the access to it. My MyCloud Single-Bay uses FW 2.31.183, maybe this helps.

Since my question concerns both devices, I am not sure which forum is the best.
I know that this is a double post, the original can be found here. But maybe an MyCloud EX2 Expert is not looking in other sections. So please be patient with me.

Greeting from Germany!
