Migrating an Existing Website from SQL Membership to ASP.NET Identity

This approach involves changing the existing database schema to the one needed by the ASP.NET Identity and hook in the old/new classes to it. After you adopt this approach, once your database is migrated, future updates to Identity will be handled effortlessly.
