Thinking about upgrading to VB Suite
 

I currently have the forum only package, and was thinking about
upgrading to the suite Blog/CMS..

Can someone please give me a brief run down on installing it..
Is it going to affect my current forum? am i going to have to
move anything around?

I have also been told that the CMS is difficult to install or work
with, is this true? as i do not want to invest hours just to
get to working properly...

I am sure those of you that already have Blog/CMS can give me
some run down on what to expect, or how to do it.
