1. Lazy way: copy whole wamp dir to somewhere else, then install new wampserver over the old one. If nothing wrong, software will be upgraded while data keep intact. If something wrong, just copy back your data.
2. Detail way: copy to somewhere else www dir in wamp dir, config.inc.php in wamp/phpmyadmin, data dir and my.ini in Wamp/mysql, and some other self created dir's, then copy them back after upgraded wampserver.
Hope this help.
