I recently changed my PC and need the replacement to become the master so that an older PC gets synced from the new one. As the older PC has no addons/extensions and only 1 tab open, the last thing I want is for it to sync what it has to the new machine which was accurately synced from the PC it just replaced.

I can find no setting in Sync to specify which machine should be the master from which all other connected devices (slaves) will get their synced data from.

Hi, PBC

I tell you that you cannot have a PC which is "master", since in Sync, everything you do on any PC will be shown on all your connected devices.

You can find more info here:

You can possibly disconnect the new device that has your data before connecting the old device to prevent syncing in the wrong direction.

You can backup your personal data.
