Does repeated .Net or azd CLI deployement of an Azure App Service over-write existing?

Hello,

I have recently deployed an Azure App Service (includes EF Core) using azd CLI.
I have a Maui App too (also includes EF Core) that uses said service to perform data sync'ing. All works.

This is still only a DEV environment, no need to preserve the Db or data (yet) so no need for migrations yet, either.

I need to make a couple changes to the Db.

If I repeat the deployment of the now existing Azure App Service using the same azd CLI steps, does that over-write that instance with the changes AND update the Db?
OR should I delete that Azure App Service with the Db OR the whole resource group and redeploy new?

Thanks
