Hey @Tuttminx I’m going to be lazy and just link you to where I’ve discussed it in a FAQ. Check out BRAVE SYNC/BACKUP & RESTORE at PSA: User FAQ - Support & Answers and you’ll see links to detailed instructions that was provided by the Rewards Product Manager with Brave, Chris (Chriscat).
Short version is just backup your /Brave folder and move it over. Make sure it’s all updated. Also, DO NOT run both browsers at the same time. If you run two active clones, it can get you flagged. This will move anything you had in your Browser over. If you’re Verified, then everything in Uphold/Gemini should still be there and all you have to worry about is getting Brave installed and then sign into the browser with your info.
Difference between the two is if you’re Verified, it should be in the system and you’ll have everything already in Uphold/Gemini. If not Verified, then you need to do manual transfer since vBAT is essentially stored on your device.
