I am trying to migrate my project to androidX. The project i am trying to migrate is based on android support libraries AppCompat. In the Developer Documentation it says tha
Switch to "Android" or "Project" tab in the file navigation window. And right click on your parent folder and go to refactor, there listed "Migrate to android" option. It is very simple. In case of any mistakes in migration we can switch back to appcompat version using "migrate to appcompat" under same menu.
