Reuse Time Machine backups following MBP migration

Hi,


I recently upgraded from my circa 2013 15" MBP running Big Sur onto my M1 16" MBP running Monterey. I used migration assistant to migrate applications, files ...etc onto the new machine. Everything looks good, however the new MBP seems unable to use the existing Time Machine disk on my NAS. I am getting the following error:


Disk XXX contains backups created on a different computer


I am going to reinstall macOS on the old MBP, hence don't need the backups for that machine anymore. Is there any way to reuse the backup, or should I just remove it and create a new backup disk on my NAS?


Thanks and regards,

Andrew

If you no longer need the backup, you don't need it and can therefore safely erase the drive.


You should however created new backups now that you have a "new" system.
