Upgrade EF 4 EDMX to EF 6 <p>My application is using a database first EDMX in EF 4. I would like to upgrade everything to EF 6. After getting EF 6 with NuGet I had to make a lot of changes to my classes that are using my EF model, because namespaces have been changed in EF 6. Then I realized, that the code generated by my EDMX does also use the wrong namespaces etc. I'm not using a custom T4 so far.</p> <p>How would I upgrade my existing EDMX to EF 6.</p> <p>Thank you.</p>
