solutions enabler 7.3.0 - upgrading from 7.1.1.0 on hpux systems

I have hpux 11iv3 and 11iv2 systems running 7.1.1.0 and will be upgrading to 7.3.0 soon to support Replication Manager 5.4.0 (that will later be installed).

Anyone have tips/caveats about 7.3.0.??? or the upgrade process??

I have reviewed the release notes and install guide...
