Migrate disks from RN314 to RN424
I have a ReadyNAS 314 with 4x3TB WD Red drives configured as X-RAID 5. I am considering adding a ReadyNAS RN424 and want to make sure that the units are compatible so that I can shut down the RN314,...
Yes, you can do that. You should keep the disk order the same.
It is advisable to put a scratch disk (must not be from your array) in the RN424, update the firmware to at least as new as what was running on the RN314, verify the update is successful (i.e. it comes up fine after the reboot), power down both units, remove the scratch disk and move your disks across. Though as both units are x86 OS6 units any firmware mismatch should be automatically corrected.
Perfect. Thank you. Now, I will also be increasing the disk size from 3TB to 4TB, each. After I have the current 4 disks up and running in the RN424, I just replace each 3TB disk, one at a time with a new 4TB disk, and allow the RAID array to resync to complete, then move on the the next disk and repeat, until all 4 disk are completed. Then reboot and I should see the increased capacity. Correct?
Again, Thanks for the help.

Basically correct, though the volume expansion begins after the second disk does it's initial resync. If that doesn't happen on it's own, then reboot at that point.
Though it is faster and simpler to set up the RN424 with the new disks, and then use the frontview backup jobs to migrate the data over the network from the RN314.
