Outlook on a New Computer

I was helping someone migrate to a new computer recently and the old computer had Office/Outlook 2007 as well as the new computer. I had successfully migrated their ~\Application Data\Microsoft\Outlook\ folder and its contents but the auto-populate auto-complete with the history wasn't working. I came across this article to determine which file was the history file but it appears that the old computer, which had earlier versions of Office had a differently named file from a fresh installation of Office, but both had the .NK2 extension so it was easy to find it.
