Entity Framework5 code first migrations is only able to manage a single DbContext per physical database instance. Now, Entity Framework6 code first migrations is able to manage multiple DbContext per physical database instance.

Code First Migrations allow you to create a new database or to update existing database based on your model classes by using Package Manager Console exist within Visual Studio 2013 or Visual Studio 2012.
ADO.NET Entity Framework is an Object/Relational Mapping (ORM) framework that enables developers to work with various relational databases like SQL Server, Oracle, DB2, MYSQL etc. It enables developers to deal with data as business objects and entities.
