iPhoto to Aperture migration?

There have been a crop of resources about migrating from iPhoto to Aperture or using the two applications together lately. I'll be taking a look as I've been using iPhoto of late to manage the photo libraries and would be interested in using Aperture some more. Today's link is to an Apple webinar on the topic. The June 2007 Macworld also has an article but the magazine is not posted on the company's site yet. Sometime soon I hope to settle on one of these tools or iView Media Pro as a means for organizing our large photo collection. As conceptualized at this point I see putting the media on a shared drive attached to an Airport Extreme base station as a shared disk.

The other shared disk will be devoted to getting rid of paper and scanning it all into a central storage location.
