zfs discuss - Jun 2007 - ZFS version 5 to version 6 fails to import or upgrade

How do you upgrade from version 5 to version 6, I had created this under snv_62
and it zpool called zones worked with snv_b63 and 10u4beta now under snv_b66 I
get error and the upgrade option does not work: any ideas?

zpool import lists the pools available for import. Maybe you need to
actually _import_ the pool first before you can upgrade.

Note that you need to specify the name (or id) of the pool.  It''ll
import
just fine once you do.  Try ''zpool import zones''.  Once
it''s imported, you
can use the upgrade command on it.
