We are upgrading our Domino clustered servers from 8.5.3 to 9.0.1. So soon we need to upgrade all of our clients to 9.0.1 from 8.5.3 FP4-6 (Multiuser standard clients).
We want to do inplace silent/unattended upgrade, so how we can achieve that?
Also there’s this blog post that talks about sequencing multiple install kits together from within a script. It has some pretty good examples of troubleshooting steps you can do as part of an upgrade.
Subject: When you install new client, it retains all user settings
Assuming you are installing into the same location and as multi-user installations, all of the previous settings and customization remain untouched. The doc you pointed out still works, but you can skip steps that are for first time setup.
