Error Booting System -- 2.4.4 (after upgrade)

So I just moved my pfsense firewall to my new server room, and after turning it back on, it failed to boot.
I shut the system down before moving it. It was a full power off.
It boots the menu screen, but trying to load the kernel fails with:
zfs io error all block copies unavailable.
Of course I start to panic ... but then I realize I can boot kernel.old ... which booted fine.
Once I got the system booted, I ran: zpool scrub zroot ... which came back with an error. Running:
zpool status -v gives me this:
[2.4.4-RELEASE][firstname.lastname@example.org]/root: zpool status -v pool: zroot state: ONLINE status: One or more devices has experienced an error resulting in data corruption. Applications may be affected. action: Restore the file in question if possible. Otherwise restore the entire pool from backup. see: http://illumos.org/msg/ZFS-8000-8A scan: scrub repaired 0 in 0h0m with 1 errors on Tue May 28 19:53:08 2019 config: NAME STATE READ WRITE CKSUM zroot ONLINE 0 0 1 ada0p4 ONLINE 0 0 25 errors: Permanent errors have been detected in the following files: //boot/kernel/kernel
Obviously it looks like my kernel is corrupt / bad. My question is. How do I fix it?
Can I just copy kernel.old over kernel? lol. I doubt this would work.
Anyways, this is a fairly new machine -- however the ssd in it is 100% new, maybe only 3months old at that ... and it's not like it gets a ton of data writes. Also, SmartData reports everything is ok.
A clean reinstall with 'Recover config.xml' option is probably the fastest way: https://docs.netgate.com/pfsense/en/latest/backup/automatically-restore-during-install.html
Before the reinstall take a Backup first just in case...
