Automatic Client upgrades after upgrading Site with Cumulative Update (CU)
When upgrading your site with a CU, have the clients automatically upgrade as well instead of creating a Package Deployment.
COMPLETED!! \o/ Well done!
Also make sure automatic client repair works, if PATCH property has been used on the command line. I've seen failures because of invalid references in LastSuccessfulInstallParams in registry.
We use SCUP with the included catalog to accomplish this. It's worked perfectly for the last 6 Updates.
