zfs discuss - Sep 2007 - Upgrading ZFS Version on Solaris 08/07

I wanted to crossgrade from OpenSolaris b65 to Solaris 10 08/07 for my main
fileserver, but I found that I could not import my zpool due to a version
mismatch.  Is there any way to upgrade only ZFS on 08/07 so that it matches
or exceeds the version used by b68?

No, this isn''t possible.  The on-disk version in b68 will be available
in S10u5.  A recent addition to the OpenSolaris source was the ability
to create a pool of a particular version for just this purpose.  But
it''s not possible to ''downgrade'' a pool, and
you''ll just have to wait
for S10u5 to get support for the latest versions.
