The upgrade scripts consist of upgrade_start and upgrade_finish, which are provided on the installation media. Use these scripts when you upgrade either of the following:
The upgrade_start script prepares the system for a Solaris upgrade, including saving the VxVM configuration data, and converting an encapsulated boot disk to a partition format.
The upgrade_finish script restores the VxVM configuration, including re-encapsulating the boot disk, if needed.
For a general VxVM upgrade, use the installvm script.
