Why each option
Two prerequisites block a vCenter Appliance upgrade: an external SSO dependency and a missing configuration export.
When the vCenter Server Appliance is configured to use an external Single Sign-On server, the in-place upgrade process cannot handle the external SSO topology and will fail, as the upgrade tool requires SSO to be in a supported co-located configuration for migration.
Exporting the appliance configuration is a mandatory pre-upgrade step; without this export, the upgrade wizard lacks the data needed to recreate appliance settings on the new version.
An embedded Platform Services Controller is a fully supported and common topology for vCenter Appliance upgrades, so it does not block the process.
Placing the ESXi host into Maintenance Mode is not a stated requirement for upgrading the vCenter Server Appliance running on that host.
