I have a web API application (.net 4.8) running on IIS.
Now I have started migrating the application to .NET core 8 and my approach is to migrate the APIs module by module as I want to follow microservice architecture.
Once a module is complete, I want my frontend app to consume the API those are completed from .NET core app which will be hosted on same IIS.
Is there any way to re route few requests to the .NET core app while keeping those which are not available in new app, route them as usual to the older app?
Is request rewrite possible here?

My requests are not directing to the new app but coming to same app even after applying rules in URL rewrite module.
