Hi John, thanks for the question,
The upgrades menu is the area where all app-related products are displayed. Currently it shows the Adventure Tier, and later this year it will show the Expedition tier for off-road and off-line tools. We also constantly improve the app, and items may be added. The upgrade section will always be there to show the services and products we provide.
Legacy Members have access to every Member Feature they have always had access to, forever. There is no need to upgrade. If you see some features or services you would like - you may upgrade at that time.
