Upgrading My Cloud Home Duo

I currently have a My Cloud Home Duo equipped with two 4 TB disk drives running in RAID 1 mode. I would like to upgrade to two 8 TB disk drives.

Is it possible the following way without losing data? Taking one 4 TB disk out, putting a 8 TB disk in and let it sync again. After that, replacing the other 4 TB disk and waiting for sync. Do I then have 8 TB capacity in total (RAID 1)?


The My Cloud Home Duo drive capacity cannot be upgraded in the field.



Thanks. What does “in the field” mean? I understand, I can upgrade drive capacity but have to accept data loss. Am I correct?

So swapping two 4 TB disks for two 8 TB disks in one rush is possible (losing data of course)?
