If you’re trying to move off of Small Business Financials and on to Dynamics GP, Jivtesh has links to the migration tool. I love posts like this because it provides exposure to the location of something buried pretty deep in CustomerSource and it makes that location visable via Google (sorry Live search, I still prefer Google for search) which means that even more people can find it.
Small Business Financials to Dynamics GP Migration
Archived post from 2008. Dynamics GP and the links it points to have changed since; check current documentation before relying on version-specific steps.
