During the last tool upgrades I made the experience, that not all changes have been documented in the user guide, installation guide or release notes.
You should please enhance the documentation and make sure, to write down exactly what we as customers should do during an upgrade process.
It would be enough if you for example write down in the release notes or installation guide, that a look into the user documentation is highly recommened or something like that.
Problem in the last upgrade procedure was that I was not aware of upgrading the mainframe-R4Z for Replicate. Now we are forced to resume the fullload.
