I have an byteball backup from 2017. How can I return the backup? Now that byteball is Obyte?
what i know is , safe the wallet.dat , and reinstall the wallet and replace the old wallet with the new one...
Don't think it works this way.
Have a look at this good article
https://steemit.com/byteball/@profchydon/how-to-perform-a-full-backup-and-restore-for-your-byte-walletIt has been written before the rebranding to Obyte but the wallet still works same way as before I guess.
So download the latest version a perform a restore from backup/fullbackup dependng on how you saved it two years ago.
