BACK UP EVERYTHING!
I have removed the old version and installed the new one.
The main probs I had/am having are the apache config and the time its going to take to get it back to how it was - fortunately I have saved my original config files so i can trall through them and put in the bits I want to keep from the old config to the new one.
I think the old version I had was apache1 and the newest package comes with apache2.
I've tried using the Perl Add-on too which doesn't work correctly as Apache2 sits in a folder called "Apache2" and the cgi-bin created by the Add-on is in a folder called "apache". TOTAL pain in the backside but fix-able in the configs.
At one point i ended up with Perl installed 3 times on my PC, all in different locations - I like Perl, but not THAT much! lol
Also, if you have installed any extra modules you will probaby have to install these all again.
Hope this helps!
