Migrating from ReadyNAS Ultra 2 (x86) to ReadyNAS 212 (ARM)

Having just acquired a 212 with it's 4-core ARM processor to replace the Atom single-core on my current Ultra 2, I am wondering how best to go about the migration from using the latter to the former.

 

Can I just swap the 2 x 3TB HDDs out of the Ultra 2 and put them in the 212? Since the Ultra 2 uses an Intel x86 CPU and the 212 uses an ARM processor, I'm guessing perhaps not.

 

I have already fired up the 212 to check it worked and both it and the Ultra 2 are running OS 6.10.3.

You can, but you need to uninstall all your apps first (since they are platform dependent).  Then reinstall them after the migration.

There is some risk, since the normal (e.g., better tested) migration path is from arm->x86, not the other way around.  In either direction, it is best to make a full backup first.

Though what I'd do myself is get new disks for the new NAS.  Then migrate the files using ReadyNAS backup jobs (one per share).  Then re-purpose the Ultra as a backup NAS.  If you go down this path, then I suggest avoiding 2-6 TB WD EFAX Red drives, as they are SMR.  Either go with 8 TB drives or larger, or go with Seagate Ironwolf.
