Hello

 

First of all "migration" is related to code-first , not DB First 

 

There is no migration needed for DB First approach .

 

For code first migration : you should write update-database if your DB have pending changes

To enable migration - automatically write following snippet in configuration.cs file: 

AutomaticMigrationsEnabled = true;
AutomaticMigrationDataLossAllowed = false;

Thanks
