HP Integrity Virtual Machines 4.3: Release Notes (5900-2265, May 2012)

11.10 Online and Offline Migration Support
The following list provides the supported online and offline migration paths for HP-UX and OpenVMS
guests:
• Support:
Forward migration — Supported between two VM Hosts running the same or subsequent
Integrity VM version (see Table 7 (page 54)).
◦
◦ Backward migration — Supported for a guest migrating back only to a VM Host running
the same Integrity VM version on which the guest was originally booted (including any
Integrity VM release patches that were installed on the original VM Host) and has not
been rebooted since. As of Integrity VM Version 4.3, a guest can also be migrated back
to a VM Host that is running a later version of Integrity VM on which the guest was
originally booted. For example, a guest booted on a VM Host running Integrity VM Version
4.2.5, then migrated to a VM Host running Version 4.3, can be migrated back to a VM
Host running version 4.2.5 (provided the guest has not been rebooted since beginning
its migration).
◦ NOTE: In addition to the restrictions shown in the following online migration path table,
the processors on the source and destination hosts must all be within one of the following
groups:
– All Integrity VM supported variants of the Itanium 2 processor prior to the 9000
– Itanium 2 9000 and the Itanium 2 9100
– Itanium 9300
