We have changed the DB endpoint in the configuration tools:

1. I have change all front end and deployment controller db endpoint and successfully applied the changes with no error logged.

2. the new DB endpoint can be accessed in the tooling server, test connection also successfully on the front end and deployment controller server

but encounter issue where the front end portal still pointing to the old DB endpoint, the changes of site properties in Service Center also doesnt applied when we called it.

Can you advise me, where I miss the step or got any other setting we need to do after the changes?
