no there is no way to upgrade due to compiler differences
save your www folder,
export your databases into sql format
keep note of any mysql users/passwords
keep a copy of the config files - http.conf php.ini my.ini if you want any custom changes.
uninstall wamp2.0c
install ms vc+= 2010 redist ( link on the download page of wamp2.2e)
install wamp2.2e ( i reccomend using the x32bit version even on a x64 machine)
