Migrate data in 1 x 12TB array to 4 x 3TB array

Featured Replies

Hi There,

   I started a journey of upgrading my server solution from an old Ubuntu NAS/Plex box to newer hardware on an Unraid trial. The Ubuntu server had a 4 x 3TB raid array setup and I copied everything over to a 12 TB (1 drive no parity) array on the new server. I ended up really liking Unraid and bought the full license and now I would like to move the old array into the current system, with the end goal of moving the 12TB drive out of the system. The problem is that there doesn't seem to be a strait forward path on how to do this. I'm looking for advice on how to move forward. 
My thoughts is that I could delete the current array, then create the new array with the 4 x 3TB drives (note I am also adding 1 x 4TB drive for parity. All drives except for the 12TB drive have been pre-cleared), and then copy the data over from the 12 TB drive to the array using the command line. 
What would you kind folks advise in this situation? Thanks in advance.

Sounds like a plan, with the Unassigned Devices plugin.

Is there an easy way to export/ import my Docker and VM configurations?

Yes, I do have a 1 TB SSD cache enabled on the server.
