9.x to 10.10: a Two-Step Process

Because of the changes to the filesystem layout that occurred at 10.0, every system upgrading from 9.x must go through a conversion process. This conversion happens during the upgrade from 9.x to 10.01.

Upgrade to 10.01 Required

A 9.x system cannot be upgraded directly to 10.10; you must upgrade to 10.01 before you can update to 10.10 or any later release.

In outline, the process looks like this:

Prepare for upgrade:
- Read Release Notes, white papers, etc.
- Do preparation tasks.
See Chapter 4 “Pre-Upgrade Tasks for All 9.x Systems”.
Upgrade to 10.01.
See Chapter 6 “Upgrading Your System from 9.x to 10.01 ”.
If you are upgrading an HP-UX cluster, run tools to upgrade the cluster clients and convert them to NFS Diskless.
See “Converting HP-UX ("DUX") Clusters”, “Preparing for Changes to HP-UX Clusters” and “Upgrading HP-UX ("DUX") Cluster Clients ”.
Load 10.01 applications and any optional 10.01 features you need.
See “Loading New 10.01 Features and HP Applications ”.
Update to 10.10.
See “Updating to 10.10 ”.
Update applications to 10.10.

New Upgrade Capabilities

Some 9.x systems could not be upgraded to 10.01 with the tools provided with the initial release of 10.01. These systems were:

HP-UX "DUX" clusters
Systems running HP-UX 9.07
Series 700 Model J systems
Series 700 C-class workstation Models C100 and C110

These systems can all now be upgraded using the tools in the package that includes this manual. (The package is labelled "HP-UX Upgrade Tools for 9.* to 10.*"; we'll refer to it as the "Upgrade Tools" package from here on.)

Using these tools you can upgrade your 9.x system to 10.01, or to 10.10 via 10.01. Unless you are running 9.07, you can choose whether to stop at 10.01 or go on to 10.10.




	CAUTION: 9.07: If you are running 9.07, you must upgrade all the way to 10.10; you can't stop at 10.01.

Table 1-1 Upgrade Paths

System/Release	Upgrade and Run 10.01?	Upgrade and Run 10.10?
9.07	no	yes
9.07 "DUX" cluster	no	yes
Other 9.x S700 "DUX" cluster	yes	yes
S700 J	yes	yes
S700 C Class C100/110	yes	yes
All other S700/800 9.x	yes	yes

You can think of the above table as a train schedule: every 9.x to 10.10 upgrade goes through 10.01, but the 9.07 train does not stop there — although these systems will in fact load a version of 10.01, that version is not supported, and must not be used, for any purpose but to get the system to 10.10.




	NOTE: As with the HP-UX operating system, HP and third party applications may also need to go through a conversion to accommodate the new filesystem layout. For this reason, if you are planning to upgrade to 10.10, you should not wait until you get to 10.10 to upgrade your applications. Upgrade applications in the same way as you upgrade HP-UX: first to 10.01, then to 10.10: Upgrade the system to 10.01. Upgrade applications to 10.01. Update the system to 10.10. Update applications to 10.10. See Chapter 7 “After the Upgrade ” for more information on upgrading applications distributed via Software Distributor, the HP utility which replaces `/etc/update`, and which you will be using to upgrade HP-UX itself. For information on analyzing and (if necessary) converting in-house code and scripts for use on 10.x, see Chapter 5 “Converting Code and Scripts ”.
