No, I don't cover migration at all. Nor do I cover AppLogics. (I know a lot about applogics, but it isn't something that I would encourage anyone to use in 2002.) I don't cover 7.0 at all either. (7.0 wasn't even in alpha when I finished writing the book.)
There is good news, however. There is a very effective migration toolkit to migrate AppLogic code to
J2EE. It leverages the iAF and is part code converter and part runtime library. Contact your local sales rep for a copy. As long as you are using S1AS/iAS the migration tool is free, although engineering does keep close tabs on the software as it's not a packaged product.
