I have 3 web servers at a client site that need to be updated, i need to upgrade the php to clear some security issues that have been hilighted.
I am running Server 2008 with IIS, the version of PHP is 18.104.22.168 (from the exe). I want to know the best way to update this and if possible a dummy guide (simple steps) along with knowing the risks to the content already in place.
The servers each are running between 40 and 100 sites so i want to ensure that any changed i make will have a minimal impact. I can take a Snapshot of the machines before hand for a roll back if required but i would like that to be a last resort.
Any support or links here would be much appreciated,
