upgrade
Since it is recommended that you uninstall your current version before installing the new one, you should make sure to copy or backup any song files/folders to another folder for safekeeping.
Other than that, you "should" be good to go - although it wouldn't hurt to e-mail MTS Support at support@multitrackstudio.com They can inform you of any specific instructions before you install.
