In the conversion phase, the logical domain uses the Oracle Solaris upgrade process to upgrade to the Oracle Solaris 10 OS. The upgrade operation removes all existing packages and installs the Oracle Solaris 10 sun4v packages, which automatically performs a sun4u-to-sun4v conversion. The convert phase can use an Oracle Solaris DVD ISO image or a network installation image. On Oracle Solaris 10 systems, you can also use the Oracle Solaris JumpStart feature to perform a fully automated upgrade operation.
