It's a full 8-hour-day job, in my experience. I've done a number of these conversions now and I've developed a set of scripts we use in-house, for both WP 1 and 2. However, no matter how many migrations I do, if I want to retain things like taxonomical hierarchies, url paths ("permalinks"), photogalleries and the like (which the client usually wants to keep), the scripts must be modifed extensively every time. In fact the majority of the work is in tweaking the scripts themselves; once the scripts are ready the actual migration takes only a couple minutes. But with the variety of WP plugins and versions out there, there is no way I'd rely on a module to do this. It requires intimate knowledge of both db schemas, and custom tweaks for every job.
