ADO.NET Entity Data Model (*.edmx) can be converted to Devart Entity Model (*.edml) with Entity Developer.

Neither *.edmx, no *.edml can be converted to Devart EF Core Model (*.efml) because it uses a different object model.

You should create a new *.efml model with Database-First approach and add the existing database objects with Create Model Wizard or Update From Database Wizard.

Thank you for your answer and attention!
EDML has some information attached to it that is not in the database, so i can't use database first way to generate efml. Now, we need to convert edml or edmx to efml.
I read EDMX by parsing XML files, is there a more stable way to do it? Such as t4.

We do not provide an out-of-the-box solution for converting EF6 model to EF Core model. Microsoft documentation about differences between EF6 and EF Core models is available at https://docs.microsoft.com/en-us/ef/efc ... /port-edmx.

I already know about this.(https://docs.microsoft.com/en-us/ef/efc ... /port-edmx)
I wonder if the templates in Entity Developer can resolve EDML?
I don't know if I can get all the EDML information in the template. such as model.Association, model.Classes and so on.
(The fornms can't upload images. The path of template is 'entity developer'->'model explorer'->'templates'->'data transfer object'.)

Where can I view the API documentation of 'entity developer templates'?

T4 template could not convert EF6 model to EF Core model. This should be a separate solution being a resource-demanding task taking into account differences between EF6 and EF Core. We recommend you to create a new *.efml model with the Database-First approach and comprehend it with your extra settings manually.
