title: How to migrate Identity users from a MVC5 app to a ASP.NET Core 2.2 app
body: <p>I have a web app built on MVC5 using Identity. I want to convert this project to a ASP.NET Core 2.2 web app. I created a new ASP.NET Core 2.2 web application with authentication set to Individual User Accounts and added my database to the project by following <a href="https://docs.microsoft.com/en-us/ef/core/get-started/aspnetcore/existing-db" rel="noreferrer">these instructions</a>. I then added a new Identity Scaffolded item to my project and added a migration and updated the database. </p>
  
  <p>I registered a test user and when I checked SQL management server I see it created a new database for this project even though my connection string is for my old database. </p>
  
  <p>I would like to keep my old database but convert it to use the new Identity Razor pages that are built in with ASP.NET Core. What is the best way to go about doing this?</p>
