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.
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.
