If the software uses normal library (chapter 3) and system (chapter 2)
call, then it probably will run on 10.20. The biggest change is the
change to System V Release 4 filesystem layout, so where things are.

See the documentation at the <http://www.docs.hp.com> site, especially:
"HP-UX 10.x" <http://www.docs.hp.com/en/hpux10.x.html> :
- "Installing and Updating", especially:
- "Upgrading from HP-UX 9.x to 10.x"
<http://www.docs.hp.com/en/B3782-90073/index.html> or PDF version
- "Release Notes", especially:
- "Release Notes for HP-UX 10.20"
<http://www.docs.hp.com/en/5964-5283/index.html> or PDF version
Note: You will probably *not* want to upgrade/update/<whatever> to
10.20, but to *install* (i.e. overwrite the disk) 10.20. But the
material above, especially the "Release Notes for HP-UX 10.20", is
needed to know what changed. Actually, you will need to know what
changed from 9.0X to 10.0[1] (the changes from 10.01 -> 10.10 -> 10.20
are much smaller). See "Chapter 4. Major Changes for HP-UX 10.0 and
10.01" in (10.20) Release Notes.
Whatever you do, make sure that have (*full*, file *and* *system* (see
mkrs(1M))) backup of the system, so that you can always go back to the
old (9.05) system, in case something goes wrong, doesn't work, etc.!

It will be hard to get the media. If/once you have the media, there is
no further cost, because nearly all system which are licensed for 9.X
are also licensed for 10.X.

If that works and is sufficient (in the long run), then that may be
the easiest path. Realize however that 9.X is totally unsupported
(since 2000, ("Y2K")). Perhaps others can comment on the current support
status of 10.20.
