7.72 How do I get rid of these old 10.X patches since I upgraded OS's?

DO NOT USE SWREMOVE!  swremove will check the scripts for the patch you
ask it to remove, and happily remove whatever file you tell it to.
Unfortunately, swinstall does not know that the patch you are asking to
remove will put back the old 10.01/10.10 file in place of the 10.10/10.20
file you just asked it to remove.

All swinstall will do is look to see, does file exist?  Yes?  replace
file with backup copy stored in /var/adm/sw/patch.  The backup copy is a
10.01/10.10 file, the file it is looking at is a 10.10/10.20 file.

The only SUPPORTED (by HP) way to remove these patches is to use the
patch_ipdcheck script provided by HP.  The script will check your IPD
(Installed Product Database) and remove all the entries for previous OS
version patches.  Then it will go remove the associated directories from
/var/adm/sw/patch.
A copy of this script can be retrieved from........ (somewhere, I don't
know where to put it.) or you can call the response center and ask
someone to e-mail it to you.

NOTE:  If you have already removed previous OS version patches with
swremove, you will either 1) need to restore from backup, or 2) reload
the OS.

According to Robert Sakic (rsakic@grc.hp.com), you can use the
cleanup (1M) program to remove old patches ... install patch
PHCO_5400 if you don't have this command allready in place.
