You don't need to use /usr/lpp/<product_name> for your mountpoint. Products have either configuration files or startup parms that point to the directory for the product. You can crate a productname directory with mountpoint directories for each of the versions and have your parms point to that directory. We do that for all of our non-root products. It works and allows quick upgrade/backoff paths. We alos use symbolic links a lot. They can make life a lot easier. Less moving parts to change.

Software upgrades are migrated from test LPARs to development LPARs to production LPARs. I think I would be expected to maintain 3 HFSs for the product (for production and 2 levels of mainteenance, I guess). /usr/lpp/<product_name>/ would point into one of the 3 HFSs; a different HFS for each type of LPAR. That doesn't address the need to switch back and forth between 2 maintenance levels since the resolved path is tied to the LPAR, but I guess I could dynamically change the value of the symbolic link if I needed to drop back to the previous level. This technique does not allow for execution of multiple levels of the product on the same LPAR, but neither does anything using /usr/lpp/<product_name>/.
