Deciding Which Method to Use
Now that you have evaluated your system and ordered any needed
hardware, you need to decide whether to cold-install or update to
HP-UX 11i v2 on your system.
NOTE If your system is already running HP-UX 11i v2, use update-ux to
update to the new version of the OE for HP-UX 11i v2.
When to Cold-Install
CAUTION The cold-install process erases software on the root volume before
installing. If you want to retain any existing software, make sure to back
up that software before migrating or use update. Cold-installing using
Ignite-UX overwrites everything on the target disk.
You can cold-install rather than update to HP-UX 11i v2 when:
• You have a new system.
• You are managing several systems with similar OS configurations.
• Your disk space needs reconfiguration. See “How to Plan Your Disk
Space Needs” on page 33.
• Your systems are organized with clean separation of the OS from
user, application, and data files.
• Overwriting the root (/) volume on existing systems will not cause a
loss of applications or data.
• Your system configuration is not listed as a supported update path.
See “Supported Update Paths to HP-UX 11i v2” on page 45.
You can cold-install from any supported configuration. See “Supported
Servers” on page 36.
