OK, this seems harder than it should be. I just bought a 2 tb hard drive and want to migrate my Time Machine volume (1 tb) to that drive. Disk Utility doesn't do it. Carbon Copy Cloner doesn't do. So what's the trick?
Nope, that doesn't work, either. (And yes, I did google it before posting). The methods do not maintain the links for some reason and when I restart TM it creates a new TM folder and attempts to do a complete backup.
