Migrating from Previous HP-UX Releases

You can cold-install HP-UX 11i v2 and its accompanying operating environment on any supported system listed in “Supported Servers and Workstations”.

You can also choose to update to HP-UX 11i v2 from any of the supported paths listed in Table 2-1 “OE Update Migration Paths to HP-UX 11i v2”. Updating from any other release directly to HP-UX 11i v2 is not supported.

If you are updating from a previous HP-UX 11i v 2 release, see “If You Have an Existing HP-UX 11i v2 System”.

Cold-install is supported on both Itanium-based HP servers and workstations. For a list of supported systems, see “Supported Servers and Workstations”.

You can cold-install from most HP-UX 11i v1.6 (B.11.22) systems and all HP-UX 11i v2 (B.11.23) systems.




	IMPORTANT: If you have an LVM-based HP-UX 11i v1.6 system, you can use an HP-UX 11i v2 Ignite-UX server to cold-install HP-UX 11i v2 on your system. If you have an VxVM-based HP-UX 11i v1.6 system, you cannot use an HP-UX 11i v2 Ignite-UX server to cold-install HP-UX 11i v2 on your system. For more details, please see the Ignite-UX web site: http://software.hp.com/products/IUX




	IMPORTANT: Update is only supported on HP Servers (see “Supported Servers and Workstations” for a list of supported servers).

Update Path Notes.

If you are planning to update to a higher level server operating environment from a current HP-UX 11i v1.6 server operating environment (for example, HP-UX 11i v1.6 Foundation OE (base OE) to HP-UX 11i v2 Enterprise OE, you must proceed using the following steps:
1. Update to HP-UX 11i v2 Foundation OE
2. Update to the desired premium OE (in this case, the Enterprise OE)
You cannot downgrade to a lower level operating environment (for example from Enterprise OE (EOE) to Foundation OE (FOE), or Technical Computing Operating Environment (TCOE) to Minimum Technical Operating Environment (MTOE)
You cannot update between server operating environments (FOE, EOE, and MCOE) and technical operating environments (MTOE, and TCOE)
