"Judging by the questions now appearing on several online forums, it seems as though many people are having problems migrating from some older Mac models to Intel Macs, particularly from Quicksilver G4's to new iMacs.I had exactly this problem with a new 24", 2.4 GHz iMac and a Quicksilver G4. Using Migration Assistant on the iMac and with the Quicksilver started in target disk mode the iMac doesn't recognize the G4. (Just curious - was the target QS drive a master?) Yes.
Migration Assistant on the iMac shows a greyed out "Continue" button in the "Restart Your Old Mac" window. And no combination of restarting and/or removing/replacing cables helps at all.
However, connected to a Powerbook G4 the Quicksilver mounted as normal in Target Disk Mode. And the iMac also mounted without problem in Target Disk Mode when connected to the Powerbook. Hmmm?
After much thought the solution was to insert another device into the firewire chain. In my case it was an external firewire CD Burner. Immediately the iMac could see the G4 and Migration Assistant successfully transferred the user accounts.
I can't explain why this worked, I just hope it helps somebody else avoid an otherwise very time consuming manual migration process.
