Today, I got an update alert from drupal to update the web from 6.13 to 6.14.

I keep forgetting the procedures (sign of getting old), so I decide to put all these things on blog, so it will remind me how to do this things and hopefully, it would help someone. I did screw up my web site when I first did the core update, so it's worth to pay attention to this.

you can find the official guide here
