I have an old MyBookLiveDuo with one defect 2 TB HDD that can’t be ordered anymore. According to the manual the disk has to be replaced with another with the same model #. I’m thinking of buying a new NAS instead.
- Can I replace both disks, one at a time, with new ones?
- If not, how do I transfer data from the old NAS to the new?
(Maybe a basic question but I’m not a computer guy… 
)
