The Upgrader tool in the Project Setup toolset can help upgrade Revit files from lower versions to the current.
It supports all Revit file types, such as Revit project files, Revit family files, Revit project template files and Revit family templates. It also provides various options to control the upgrading process and the output results.
If the output folder does not exist, after the OK button is pressed, a message box will appear to confirm.
A progress bar will be shown to indicate the progress of the upgrading. If the progress is not as expected, the Cancel button can be clicked to cancel the upgrading.
Finally, an information box will appear to indicate what have been done and what might be wrong.
