How can I safely upgrade my UGREEN DXP2800 from 2×4TB to 2×12TB RAID 1 without data loss?

  • Hey everyone,

    I’m currently using a UGREEN DXP2800 NAS with two 4TB drives in a RAID 1 setup. Now I want to upgrade to two 12TB drives, also in RAID 1, and ideally do this without any data loss.

    I’ve already made a manual backup by copying all files to an external drive (drag & drop).

    What’s the safest way to upgrade to the 12TB drives while preserving the RAID 1 setup and my data?

    Should I try swapping the drives one by one and let the RAID rebuild? Or is it better to just do a clean setup with the 12TB drives and restore from the backup?

    Any advice or experiences with this specific NAS would be much appreciated!

    Thanks in advance!
