Migrating from vPars A.03.xx to Mixed HP-UX 11i v1/v2/v3 vPars (A.03.05, A.04.02 or later, A.05.03)

This section provides an overview of the process for migrating from an existing vPars A.03.xx environment to a mixed HP-UX 11i v1/v2/v3 vPars environment. A mixed HP-UX 11i v1/v2/v3 vPars environment supports virtual partitions running vPars A.05.03 on HP-UX 11i v3 (11.31), virtual partitions running vPars A.04.02 or later on HP-UX 11i v2 (11.23), and virtual partitions running vPars A.03.05 on HP-UX 11i v1 (11.11).

For information on using a mixed HP-UX 11i v1/v2/v3 vPars environment, see “Mixed HP-UX 11i v1/v2/v3 vPars Environments in vPars A.05.03”.

Two approaches are available for migrating to a mixed HP-UX 11i v1/v2/v3 vPars environment:

See the Migrating from HP-UX 11i v1 Virtual Partitions to a Mixed HP-UX Version Environment white paper at http://docs.hp.com for a further detail and a description of the steps and choices involved in these migration paths from a vPars A.03.xx environment to a mixed HP-UX 11i v1/v2/v3 vPars environment.

Before beginning the migration to a mixed HP-UX 11i v1/v2/v3 vPars environment it is critical to confirm that system resources can support the HP-UX 11i and vPars requirements, including:

All virtual partitions that will remain as HP-UX 11i v1 virtual partitions after the migration must update to vPars A.03.05. The HP-UX 11i v2 virtual partitions can be at vPars A.04.02 or greater, but depending on the migration path they might all be updated to vPars A.04.05. All HP-UX 11i v 3 virtual partitions will be at vPars A.05.03 once the migration to a mixed HP-UX 11i v1/v2/v3 vPars environment is complete.

	NOTE: In a mixed HP-UX 11i v1/v2/v3 vPars environment, all HP-UX 11i v1 vPars must be updated to vPars A.03.05. However, before vPars A.03.05 is installed, you must install iCAP version 8.03 on each HP-UX 11i v1 virtual partition. This will also install the required versions of WBEM and NParProvider and necessary patches. Installing iCAP 8.03 onto an HP-UX 11i v1 system running versions of vPars prior to A.03.05 will exhibit an error message which can be ignored, and you can proceed with updating the vPars software. After the vPars installation, you must go to each HP-UX 11i v1 virtual partition and run the command swconfig -v B9073BA to complete the iCAP installation.

	CAUTION: Designated-Admin Feature and Mixed HP-UX 11i v1/v2/v3 vPars Environments  In a mixed HP-UX 11i v1/v2/v3 vPars environment, configure only virtual partitions containing vPars A.05.03 as designated-admin virtual partitions. Within a mixed HP-UX 11i v1/v2/v3 vPars environment, only the HP-UX 11i v3 virtual partitions (containing vPars A.05.03) can modify other virtual partitions via the vparmodify command, and only HP-UX 11i v3 virtual partitions can use vparcreate and vparremove to create and remove other virtual partitions. If you use the designated-admin feature and configure only HP-UX 11i v1 and/or 11i v2 virtual partitions as designated-admin virtual partitions, no virtual partition will be able to modify other virtual partitions.
