Migration from true Nas to zima

Hi there

I currently use True Nas Scale and I am thinking about migrating across to zima os.

However I am undecided.

Can all you lovely users advise on the following

  1. Sticking with Zfs with zima os but installing new hdds and then important the data from my old.
  2. Or moving to snap raid or mdma
  3. Which is the better option.

I believe the safest option is to install new HDDs in ZimaOS, set the storage up fresh, then copy/import the data from the old system. That way your original disks stay untouched until everything is confirmed working.

My suggestion would be:

ZFS if the data is important and you want integrity, snapshots, and scrubs.

mdadm if you want a simpler traditional RAID setup.

SnapRAID if it is mostly media/archive storage that does not change often.

For important data, I’d personally lean toward ZFS, but only if you are comfortable managing it properly on ZimaOS.
