What is difference between Ax 2012 R3 and D 365?

Please anyone know reply me…

You would need to start looking at the release notes. The obvious difference being azure based and ui.

docs.microsoft.com/…/index

There are so many differences, in architecture, functionality, ways to customize the application, deployment, licensing… It can’t be answered comprehensively.

Fortunately you can get some idea from the documentation: What’s new or changed.

Thank you martin Dra’b for given valuable information…

The release cycle and support requirements too for sure. Almost everything is changed in the way you own and maintain your ERP now.
