Post Fangtooth upgrade, can't destroy invalid duplicate boot-pool

OpenZFS TrueNAS
1

I just performed a TrueNAS upgrade via the GUI from 24.10.2.4 (EE) to 25.04.2.6 (FT).

When it rebooted after the upgrade, I’m now getting an error when it tries to import “boot-pool”

It says there are more than one pool named boot-pool and to mount the correct one by ID and then exit. /sbin/zpool import shows both boot-pools (and the data pool). One boot-pool is the proper one and the other looks like so:

  pool: boot-pool
    id: 1885521082526155599
 state: UNAVAIL
status: One or more devices contains corrupted data.
action: The pool cannot be imported due to damaged devices or data.
   see: https://openzfs.github.io/openzfs-docs/msg/ZFS-8000-5E
config:

        boot-pool    UNAVAIL  insufficient replicas
          nvme0n1p4  UNAVAIL  invalid label

It is indeed invalid as the partition it’s pointing to is the swap partition. I’m now stuck. I can’t rename it with zpool import because it’s invalid and won’t import and I can’t zpool destroy it using the ID. Obviously I don’t want to destroy it by name because real boot-pool would likely go poof.

I could really use some suggestions.

Thanks in advance
