I'm working on updating an old system, and we're introducing Entity Framework for some new functionality. The system is, however, too large to do the migration in one step, so I would like to do some testing in another database before updating the db schema.
I have created an empty model, included a couple of tables from the database, and added a couple of new entities from scratch, along with relationships between these entities and the old tables. Now I want to create a new database schema in another database with my desing model, but I can't figure out how to switch so that clicking "Update database from model..." won't work with the old database, but the with the new one.
Is there a straight-forward way to do this?
