How to move backup from one computer to the other

Copy the backups folder and paste it in the new location. If it’s the same location, ~/Library/Containers/ then it’s fine.

Otherwise, go to Settings –> Under Backup Location, click on “Change”. Make sure that inside your new location you have your Horcrux “backups” folder inside it.
Path Horcrux
Go to Keychain Access.app, search for “Horcrux” export and then import. If you have iCloud Keychain. You don’t even have to do that.
We’re working on a “Export Horcrux” and “Import Horcrux” system. So, stay tuned.
