– Enables advanced capabilities such as SMT4, Live Application Mobility and Live Partition Mobility
– Provides a way for AIX 5.2 or AIX 5.3 clients to move up to POWER7
AIX levels supported are final service packs of final TLs: 5200-10-08 or 5300-12-04
SWMA provides limited support for AIX 5.2 or AIX 5.3 including phone support and limited new fix
support
– Fix support is limited to security, data integrity problems and critical issues and may not always be possible
WPAR restrictions apply:
– HACMP support only for the global instance
