Great question, quick answer:
Yes, we already do. Every asset listed on jpg is also listed on Wayup as we speak, as we aggregate everything.
This means even if the jpg UI shuts down, you will still be able to purchase listed assets through Wayup.
Additionally, we have a built in migration button. Can be found in the Listings tab of the User Profile.
Can you work with the JPG team and have all data transferred seamlessly?
