you need to make a copy of the www folder and move it outisde of the wamp directory.
you need to export all your databases into sql format.
if you had made any changes to the php.ini , my.ini or httpd.conf keep a copy of those so you can check which modules/extensions had been enabled.
then you can uninstall. and delete the wamp folder.
then install wampserver2.2e (i recommend 32bit even on a 64bit machine)
then replace your www folder and import your sql file.
Addons would have been continued but once you are using 2.2e you can install 2.2f etc directly on top so no need for addons.
if you get stuck or are unsure, i can take a look with TeamViewer
