Have you reviewed UPGRADING-3.6 UPGRADING-3.8 UPGRADING-4.0 shipped in RT4's docs/ directory and also available on http://docs.bestpractical.com ? They provide our recommended upgrade path. Step 2 and 6b of the README also lay out similar information and pointers. There's also a blog post laying out pointers to the information provided in all of those documents. http://blog.bestpractical.com/2011/07/upgrading-to-rt-4.html -kevin
