You would of course want to review the changes between the release and do normal testing in your environment as appropriate.

As far as the installation of the software itself -
You would migrate to the new LOADLIB modules by copying or some other technique.

For the UNIX installation directory, you can install into a release-specific directory name, like:


and then have a symlink:

/usr/lpp/coz -> /usr/lpp/coz2.4.5

So that when you install a new release in:


You can implement it by changing the symlink to:

/usr/lpp/coz -> /usr/lpp/coz3.0.1

Note: this assumes that you have not customized any of the sample scripts in the install/sample directory, or if you did you either moved them to some other directory. Otherwise, you will need to roll any customizations forward to the new release directory.
