Migrating to HP-UX 11i
Changing Operating Environments
OE from the latest set of HP-UX 11i CDs, then use swremove to remove
the unwanted OE bundle and its software. For example, to move from the
64-bit Mission Critical OE to the 64-bit default 11i OE:
Step 1. As root, add default HP-UX 11i OE (in this example from CD1 and CD2
mounted, in turn, at /cdrom):
/usr/sbin/update-ux -s /cdrom -y HPUX11i-OE
The -y option tells update-ux to ignore warning messages and complete
the update.
Step 2. Remove the Mission Critical software:
/usr/sbin/swremove HPUX11i-OE-MC
This command removes the IPD entries and software for the additional
(superset) software in the Mission Critical OE, leaving the default
HP-UX 11i OE software intact.
