EF 5 - The first model, how to update the database schema without resetting the database

Question

I am developing in MVC 4, EF 5.0

Model First development - how can I easily get the database schema for updating without dropping the database / erasing any data?

eg. I have a Customer table. In this table, we record the first name, last name, email address. Now I want to get a phone number, so I change the model and get EF to update the database schema.

Visual studio 2012 refers to http://go.microsoft.com/fwlink/?LinkId=238269 , however for me it looks like Chinese.

They talk about launching the NUGET package, called the first code transfer. This feature does not ship automatically with VS2012?

thanks

Database migrations are what you are looking for. Both automatic and specified in the code - http://msdn.microsoft.com/pl-PL/data/jj591621
