Compatibility of discs running in failed ReadyNas RN104 with new ReadyNas RN214

My first comment is that the only way to keep your data safe is to back it up on other device(s).  All devices (from any manufacturer) can fail, and RAID is not enough to keep your data safe.

XRAID is a wrapper built on standard linux tools - in particular linux mdadm software RAID and the BTRFS file system.  There is nothing proprietary.  The data can be extracted from a standard x86 linux system, and it can also be extracted from some data recovery tools - for instance ReclaiMe.

my question is, if I purchase a new ReadyNAS RN214, can I simply remove the discs that were running in the RN104 and move them to the RN214 (placing them in the same left to right order)? The discs are (4) 4TB WD Red NAS Hard Drives.

If the failure (whatever it was) didn't damage the filesystems on the disk, then you can directly migrate the disks to a new OS 6 ReadyNAS - including the RN214.

My current RN104, purchased in Feb 2014 and therefore out of warranty, will not boot up, instead giving a "Fail to boot from USB!" message even when trying to boot from USB. I have the most recent upgrade to OS 6.9.1, and it was running fine as two days ago.  However, when removing the USB boot drive and starting the machine per normal, the same "Fail to boot from USB" error occurs.

Can you try removing all disks (including USB drives and any other USB connections), and power it up diskless.  Then tell us what status you see on the front panel, and also the status reported by RAIDar ( https://kb.netgear.com/20684/ReadyNAS-Downloads#raidar ).
