Migration Assistant - What You Need to Copy Data From an Earlier OS

Apple’s Migration Assistant makes it easy to copy user data, user accounts, applications, and computer settings from an earlier version of OS X.

Migration Assistant supports numerous ways of transferring the necessary data to your new installation of OS X Leopard. The method used in this guide will allow you to transfer data from an existing hard drive volume that contains an earlier version of OS X to a new Leopard installation that’s located on a separate hard drive volume on the same computer.

There are currently two versions of Migration Assistant available for Leopard. Version 1.1.x is included on Leopard Install DVDs; version 1.2.x was included in the OS X 10.5.3 update. The two versions are very similar, with just a few text changes in the names of options, and a new feature in 1.2.x that lets you use your network to transfer data between computers. With previous versions, you could only do that with a FireWire connection, using Target Disk Mode.

This guide uses version 1.1.x, on the assumption that this is a fresh install of Leopard (OS X 10.5.1) that has not been updated yet.

What You Need

  • A fully operational installation of OS X Leopard.

  • A previous version of OS X, located on a separate volume on the same Mac.

  • About 30 minutes to 1 hour of your time. The amount of time the process will take depends primarily on how much data is being transferred.
