Hi
I need to re-start my server after making some changes to php.ini

I'm wondering what is the best practice for doing this on a live production site. Im running e-commerce site with ubercart, so i dont want to push the re-boot button when someone is in the middle of a purchase... or some other process is running.

Is it best to put the site into maintenance mode and then do it? Is there some sort of safer/easier/gentler way to do a re-start?

thanks
