Migration is possible only in cases when the original file can be imported on the new version of the program. Since we're talking about the same application, I believe they're compatible "out of the box" without doing something else. If you have the software installed, open it and go to File > Open or File > Import then select the files that have been created in the previous version of the software.
You can also check what file types can be imported into the application through the File > Open dialog.
