I don't recomment MicroTools. I worked for a company a while back where we had the same problem. Unless MicroTools has made significant improvements to their product, it spits out garbage last I checked.
What we found was that pretty much any upgrade path will require significant amounts of coding changes. All these tools are good for is to maintain a similar GUI from the original application. Their code had no object structure, just a bunch of utility functions that were dumped on each page to simulate the way Access provides record navigation. If you have a large number of forms, pulling out their solution and implementing your own takes some work and a ton of find-and-replace operations.
We were so disappointed with MicroTools performance that we started writing our own converter. We were pumping out better ASP.NET forms than they were after a week of coding.
