Upgrading from FreeBSD10-B3 to FreeBSD10-RC1 borked

[Zenny]

Thanks Devin for your hints:

However, for others who had similar problems I am adding some changes
to your step-by-step instructions:

Step 1. Boot into LiveCD

Step 2. Execute the following commands...
        mkdir /tmp/bootpool
        zpool import -f bootpool (without -f option it refuses to import)
        zfs set mountpoint=/tmp/bootpool bootpool
        zfs mount -a
        cp /tmp/bootpool/boot/encryption.key /tmp/
        zfs umount -a
        zfs set mountpoint=/bootpool bootpool
        zpool export bootpool (changed from zfs to zpool)
        geli attach -k /tmp/encryption.key /dev/ada0p3
        geli attach -k /tmp/encryption.key /dev/ada1p3
        # NB: Substitute ada0p3 for proper disk
        # NB: Repeat for each disk in the zroot pool
        zpool import

At this point, the final "zpool import" shows the zroot.

Is there a version-specific instructions to recover the borked
environment in FreeBSD10 after the above steps?

Thank you again!
