FYI - installers may be manually run (can copy between machines easily), and if not authorized, SONAR comes up in DEMO mode by default. Both online (CCC) and offline options exist for authorization of purchased SONAR.
For SONAR 7 effects you can do a manual installation and install only plugins (if desired). You may want to keep that installed side-by-side with the new SONAR as you come up to speed on the new GUI/features.
