For simple migration, it's not typically a major task. I cannot even remember what changes I made several months back when I did this to one of my major apps. The app itself runs unchanged on both Tomcat6 and Tomcat.
Obviously, if you want to start exploiting features that are new to Tomcat7 it can get more complicated, but a straight port shouldn't be too traumatic.
The secret of how to be miserable is to constantly expect things are going to happen the way that they are "supposed" to happen.
You can have faith, which carries the understanding that you may be disappointed. Then there's being a willfully-blind idiot, which virtually guarantees it.
