Migration Automaton

The migration automaton can easily perform OS upgrades (upgrade from AIX 6.1 to 7.1 or 7.2, upgrade from AIX 7.1 to 7.2). The migration is performed on the NIM server, so that the system is still available during migration. The migration is done by means of an alternate disk copy, in case of an error the original version of the operating system can be easily rebooted.
