IMac – Bought a new iMac to replace the old, have two questions regarding file migration

I've migrated between many macs over the years, and I've always found that the best way to do it, is manually. Normally I use a firewire cable (but you can also use WiFi, USB, external hard drive, dvd/cd, etc) to hook up the two computers, then just drag over files from one computer to the other.

Mostly everything the average user has on their mac will be found in their user folder (home folder). You can just drag/copy this entire folder over, or you can be more selective about which folders in your home folder you move (for instance, you may not want the Library folder). Then, anything outside of your home folder (Applications, for one) you can drag/copy over if you want.

Yes, if you're fresh installing the new Mac it will ask if you want to transfer information at the end of the install process - just have a firewire to firewire cable handy and have the old mac booted into target disk mode (hold down T while the old mac is booting up).

Just check you can boot the old mac into target mode first - I know some of those old macs weren't built with the capability. If you can't target mode just comment on the answer or your question, there are other ways around this.

The only gotcha I can think of is any PPC apps (ones that use the older Power PC processors) like AppleWorks will need to use Rosetta to run, which might make them run a bit slow or cause general funkyness with those apps. You'll want to upgrade your Dad's apps to their Intel versions if you can - using something like App Fresh after the migration would be a good idea.
