If you've been connecting to your legacy database, please follow the steps here to re-migrate and ensure that you switch over your connection strings afterwards.

im not connected to legccy it had been stopped
and i connect to the new one but it have an old data

the new database has old data because you have stayed connected to the legacy database, follow the links ray has provided for the solution

you mean connect my app to the private url database first

Hey, can you paste a link your project here please?

as ray said, you need to re-migrate the legacy database, the first link he provided tells you how to do that, then you need to switch over all your hardcoded database credentials to the new database, the second link he provided tells you how to do that.
