I'm still somewhat of a newbie to GWT, but I've been using it (along with Eclipse) for the past few months to port a desktop application to the browser. I'd started with GWT 1.3, but all signs seem to indicate that I should start using 1.4 before I get too much further, so that's what I plan to do. The problem is that I can't find any resources on what's involved with making such a migration. Is it a simple matter of swapping out a few JARs? Should I create a whole new project and copy over the code?

All you need to do is change out the GWT jars. The GWT 1.4 loading mechanism has changed, but it is still backwards compatible with the 1.3 loading style (using the module meta tag).

In most cases this will be enough... but you may find that there were some API changes that affect you. In general though the API changes are minor, and easy to fix.

I suggest just trying it and see if it works.
 
Don't get me started about those stupid light bulbs.
