I need to use the migration assistant to restore a user. Unfortunately, I need to do this from an older backup. This answer suggests this can be done by moving the more recent backup files. I tried this using Finder but given an alert that this action was not authorised. I checked at the Genius Bar, and they say that on Catalina, moving the files is deliberately blocked because the consistency of older backups is not ensured.
I am in a situation where I am prepared to risk that the restoration leaves an inconsistent machine, so I am wondering if using Terminal with admin privileges, I can move the more recent backups?
