How to Upgrade WD Red Pro NAS Internal Drives on MyCloudEX2 Ultra

I have the WD MyCloud Expert EX2 Ultra with drive capacity 2TB x 2.

I have purchased 10TB x 2 WD Red Pro NAS internal drives to allow for an array with good storage.

Currently, the configuration is a RAID volume (Volume_1) spanning with 3.92TB (3.49TB free).

What would be the procedure to ensure that the data on the original drives is migrated/copied to the new drives?

Example: Do I take one original 2TB drive out and put 1 new 10TB drive in and change the configuration RAID model to a NAS (so it copies the content to the new drive followed by replacing the second original 2TB drive when it is completed?)

Any help on correct procedure would be most appreciated.

You’re in the wrong sub-forum asking for help. This is for the single bay/single drive WDMYCLOUD.

Thank you. I will adjust.

Spanning? Such that if one drive is kaput. . .all the data goes poof?

Yeah. . .I think the best answer in this case is to copy all the data to another unit (HDD/PC/Onedrive. . .whatever). Then install the new drives. . .then copy the data back to the NAS.

I would consider using JBOD instead of spanning to avoid the common mode failure problem (unless access speed is super burning critical)

You pretty much have to back up the current 2x2Tb of data to an external drive. Then replace the 2TB drives with the larger drives and reload the data from your backup source.
