What happens to the libraries and objects in my AC 12 file when I open the file in AC 13?
Your “Local Libraries” from AC 12 automatically become linked libraries in AC 13.
Your “other objects” from AC 12 become Embedded Objects in AC 13.
Any “missing objects” in the AC 12 file are listed in a separate “missing objects” folder in AC 13’s Library Manager. In this case, if you know the location of the missing object file, use Library Manager’s add function to browse to the file and add it to the Embedded Library.
* If you want to work with your migrated file in teamwork mode, then you need to re-organize your libraries – you need to move project-specific objects to the embedded library.
