Hi guys, I've been running very old 0.7.19 nginx with virtual host configuration for ages now with nginx.conf listed below. But it's time to upgrade to 0.8.20 so what's the best way to do this AND be able to backup 0.7.19 nginx (which specific files) so I could ASAP switch back to 0.7.19 to get things running if I mess up 0.8.20 install ?

Also not sure if my settings in conf files below are correct for 0.8.20 syntax/format etc wise ?

Any help is appreciated :)
