2.3 Upgrading the VM Host from Previous Versions of Integrity VM V3.X
to Integrity VM V4.2
Integrity VM Version 4.2 VM Host requires the HP-UX 11i v3 operating system. Only HP-UX
11i v2 servers running Integrity VM Version 3.0 or Version 3.5 can be upgraded to the HP-UX
11i v3 Integrity VM Version 4.2 release. This section describes the process to follow when
upgrading an HP-UX 11i v2 based Integrity VM server to an HP-UX 11i v3 based Integrity VM
server. If you are upgraded the VM Host from Integrity VM V4.0 to Integrity VM V4.2, see
Section 2.4.
HP-UX 11i v3 supports many features that are backward compatible with 11i v2, allowing 11i
v2 applications to run without modifications. The primary goal of this section is to provide
direction to the administrator performing the upgrade of the VM Host to make sure that all
configured virtual machines (guests) boot and run after completing the upgrade to 11i v3.
Figure 2-1 provides a flowchart of the upgrade procedure from 11i v2 to 11i v3.
