x86: Cannot Use Solaris 9 12/03 (x86 Platform Edition) Installation CD to Upgrade x86 Systems From Solaris 2.6 or Solaris 7 Software

You cannot use the Solaris 9 12/03 (x86 Platform Edition) Installation CD to upgrade x86-based systems from the Solaris 2.6 or the Solaris 7 software to the Solaris 9 12/03 release. The upgrade cannot be performed because of the x86 boot-partition requirement.

Workaround: On x86-based systems, use the Solaris 9 12/03 Software (x86 Platform Edition) 1 of 2 CD to upgrade from the Solaris 2.6 or the Solaris 7 software to the Solaris 9 12/03 release.
