HD Upgrade
I currently have four 4-TB drives in a RAID 5 configuration, with around 10TB of content. I am looking to replace them with larger drives (12TB). I want to verify the procedure I have in mind as be...
If you aren't using XRAID, then switch to that first. It will be a bit simpler.
The procedure is correct, but the NAS will automatically expand during the resync of the second drive. If it doesn't expand at that point, reboot the NAS - that should trigger it. It will expand again when resyncing the third and fourth drives.
Also, you will need to format the last drive on the volume page before the system will add it to the volume.
After you are done with this project, you should consider putting a backup plan in place for the NAS.
It's a sound plan so long as one of drives 1-3 doesn't fail during the resync of the 4th. While one does not usually expect that with new drives, most drives either fail very early or last their intended life.

Yes, I agree that's a risk. You could of course leave slot 4 empty, and use the fourth disk for NAS backup for now.
RAID isn't enough to keep your data safe, so you do need to consider how to back up the NAS regularly.
