Incorrect comment - Correct term is Live Application Mobility
"The key WPAR program that IBM is adding into the Enterprise Edition release is called Workload Partition Manager, which was previously an add-on product, and this is what allows AIX WPARs and their workloads to be teleported from one physical machine to another using what IBM calls Live Partition Mobility."
Live Partition Mobility - Introduced with Power6 systems and migrates the entire partition including the OS. It is initiated and managed by the HMC (Hardware Management Console)
Live application mobility - migrates a WPAR to another machine or LPAR, feature of AIX 6 (and can thus be done even on Power4 or Power5 systems)
