HP-UX 10.20 and 11.00 mixed environment

[Bruce Baillie]

I am forced by my application vender to upgrade all workstations from HP-UX 10.20 to HP-UX 11.00. I have a NFS/NIS server and many client network. I do not plan on using NIS+. Will a mixture of OS versions work in this environment?

Strictly speaking about the OS, they are compatible. We have NFS, NIS, etc.
running from 10.20 to 11.00 and 11.00 to 10.20 without trouble. My worry would be the apps.

Hi Bruce,

There is no problem with having different OS versions of HPUX, using NFS, NIS, etc, but where you might have problem is with your applications.

[Bruce Baillie]

Thanks for the help. Fortunately my application will run on both OS versions, but the next release will only run on V11.00

If you use NFS mounted home directories, then you
may have trouble using the same home directory
for both 10.20 and 11.0 CDE logins. The format
of CDE session files has changed in 11.0, so
switching back and forth can loose session data.
You can create a directory per client name so that
different clients running different OS levels will keep
their session data separate from eachother under
one home directory. To do that, copy the session
data to directories with names based on the
DISPLAY for each host.
for d in sysA sysB sysC
do
cp -R ~/.dt/sessions ~/.dt/${d}:0
done

Good point, Mike but I do not NFS mount home directories.
Thanks
