Solaris 10 Update 10 attach -U ERRORS

Hi there,

 i would appreciate if i can get a workaround for the following problem. I had a succesful upgrade (Update 10). However, when i tried to attach -U of the zone the following errors occurred:

zoneadm: zone 'sbw1ad': ERROR: attempt to downgrade package SUNWservicetagr 1.1.4,REV=2008.04.25.09.06 to
version 1.0,REV=2007.05.21.20.36
zoneadm: zone 'sbw1ad': ERROR: attempt to downgrade package SUNWservicetagu 1.1.4,REV=2008.04.25.09.06 to
version 1.0,REV=2007.05.21.20.36
zoneadm: zone 'sbw1ad': ERROR: attempt to downgrade package SUNWstosreg 1.1.4,REV=2008.04.25.09.06 to
version 1.0,REV=2007.05.21.20.36

please advise what action i can take to get the zone attached.

thanks in advance,

Thewie.
