"Make a full backup and turn off auto login for your account Create a 2nd admin user for purposes of changing the path once you are booted into the SSD. Create a custom copy script in SuperDuper! Allow the user to select the script in the first tab. Include the script ""Backup - all files.dset"" in the second tab. On the third tab set an ignore for /Users/yourusername In SuperDuper! use this script to copy from the HD to the SSD. It will leave all data on the HD, and copy everything but your user folder to the SSD. Change the boot drive to be the SSD in System Preferences. Boot into the SSD, login to the account you created in step 2, and follow knweiss's advice from the page you linked to. You'll be right clicking on your account to change the path to point to the user folder on the HD. Reboot and login.
Be aware that you'll have a /Users folder on your SSD which will have /Shared in it, and new users will be created on the SSD unless you specify otherwise.
Once you are done you should delete everything on the HD except of course /Users/yourusername
Don't change the name of the HD in the finder or it will break the link to your User folder unless you edit the link again in Accounts. You can change the drive name before you start, but pick something you'll want to stick with."
