Only necessary if the pool is upgraded, which was not the case.

Don't upgrade the pool for now, you have problems to solve first.
Then, you'll be able to upgrade the pool, and don't forget to also
update the zfs boot code before rebooting (see UPDATING). Don't forget
you won't be able to import your (upgraded) v28 pool with a
8.2-RELEASE if you have problems with 8-STABLE ! Also, you can use
mfsbsd if you shoot yourself in the foot.
