I currently have a D-Link DNS-320 with 2x2TB HDDs in there, setup with Raid. Am not at all happy with the speed of the D-Link unit - working in a Mac environment. So after a lot of research I settled on the Synology DS212j NAS.

Now my question is this - is it possible to just unplug the D-Link, remove the drives and pop them into the Synology unit and power it up? If so, is there anything I need to do in preparation.

If not, what's the best way of doing this. I don't have other drives in the Synology - my hope was to take the 2 in the D-Link and move them into the Synology and be done with the D-Link.

Right now, I have backups, photos, videos, etc. on the HDDs in the D-Link. I can't afford to lose anything on the drives.

Any help would be most appreciated. Many thanks.

Moving the disks from one NAS to another NAS (esp. another brand/completely different) NAS is not guaranteed to work.Do not do that without making a backup.

Ok, now that is said, you have three options:

  1. With enough drives (e.g. four 2TB drives):
    - Put the new drives in the new NAS.
    - Format the new NAS.
    - Copy the files.
    - Keep the old NAS as an off-line backup. Preferably in another location.
  2. With only the two 2TB drives and enough space for a backup:
    - Verify that the backup works.
    - Put the drives in the new NAS.
    - If they work there. Great!
    If not reformat and copy the data to the new NAS.
  3. With only the two 2TB drives and insufficient space to make backups.
    Do not test this without backup. Really. Borrow a friends drive, or move all data to one 2TB disk and move the disks across one by one, or any other way. But doing it without a backup risks all your data.

Thank you for the response. Perhaps I need to buy another external drive to backup the NAS drives before attempting this. If only I didn't have a lifetime (my children's) of photos and videos on there, I would try it out, but as I said I can't afford to lose any of that! :) – Mo Boho Jan 20 '13 at 14:08
I'm curious though, has anyone tried moving drives from one NAS to a different brand NAS and had any issues? – Mo Boho Jan 20 '13 at 14:13
I have done it, but I wiped the drives before I moved them. So I guess that that does not count. – Hennes Jan 20 '13 at 14:50
@MoBoho its highly unlikely to work, the brands all use different raid (and pseudo raid) setups and generally not all use the same filesystem either. – cjb110 Apr 15 at 7:16

Wiping drives when transferring from one brand to another brand (or even within brands) is the general expected behaviour in my experience. Different file systems, security, and 'operating systems' mean that a swap can't be done. I'll be more than happy to be proved wrong, though.
