My parents used to have two Macs...a "iLamp-style" iMac for my Dad, and an iBook G4 for my Mom. A while back, I had setup the iMac to have an external Firewire Hard Drive for a Time Machine Volume, and backed up both the iMac and iBook to that drive.

Recently, the iBook died and the iMac was really slow to work with. So my parents decided to replace the iBook with an iPad, and also purchased a Mac Mini.

I need to help my parents get their data from their two computers (backed up by Time Machine) onto the same machine. Pretty much everything is identical between the two systems (same apps, etc), however, they both have individual email accounts and photos that they want to retain.

Is it possible to do two Time Machine restores onto one computer?
