The way Brave stores user settings, passwords, and bookmarks is too cryptic for me to easily figure out.
1). Backup /home/user to a remote drive, including hidden directories/files.
2). Install an upgraded OS (Debian Buster) from scratch.
3). Try to figure out how to get all the user stuff back for Brave Browser from the backup.
Crypto-currency and rewards stuff you can leave out. I never figured out how to work that.
Be able to restore the correct files from the backup, so Brave is like it was in the previous system.
I have found Brave-related files in backup of ~/.cache, ~/.config and ~/.local. Can I simply copy those files from the backup to the new installation, launch Brave Browser, and it will pick everything up?
