Entity Framework 4.3 Data Migration by Scott Guthrie

What is EF Migrations? If you are using Entity Framework Code-First, Migrations allows you to update your database schema to reflect your POCO classes without having to drop and recreate them. This involves DDL statements to create new tables/columns, alter existing ones, etc. which get generated. The feature has been available to developers for a while as a Nuget package (which can be still used if you are using a lower version of Entity Framework for legacy reasons), but not formally supported by Microsoft.
