Hi,
the Web Services for System Center 2019 Orchestrator are nearly the same as for 2012R2.
Microsoft recommends (https://video2.skills-academy.com/en-us/system-center/orchestrator/release-notes-orch?source=recommendations&view=sc-orch-2022#service-manager-connector-doesnt-work-with-new-web-api):
Service Manager connector doesn't work with new Web API
Description: Service Manager (SM) console doesn't detect Orchestrator 2022 installation because the Connector for the new Web API is yet to be released.
Workaround: Install the Orchestrator 2019 Web features on the computer alongside Orchestrator 2022. Ensure to configure the Orchestrator 2022 database in the 2019 Web features. The SM connector can monitor Orchestrator 2022 with Orchestrator 2019 Web service.
So, I would use the 2019 Web features as well ...
Regards,
Strefan
