John, I think that Russell is suggesting that you temporarily move the iMac G5's internal drive to the Firewire enclosure. Then connect the Firewire enclosure to the new Mac and run the Migration Assistant. Then return the drive to the old iMac. Another variant: Connect your external USB the iMac G5. Run a disk cloner to make the USB drive a copy of the iMac internal drive. Now move the disk drive out of the USB enclosure and into the Firewire enclosure. Plug Firewire enclosure into the new Mac and run Migration Assistant. As far as system files are concerned... Migration Assistant will know what to copy and what to leave behind. It will capture the important configuration files, preferences, etc., etc. Applications that are PPC only will also be copied and since they can be executed on the new Mac via Rosetta. Once you resolve the Firewire connection, the rest should go smoothly. Mike >The "old" iMac G5 still works just fine except that the Firewire >ports don't work.
