How to convert a site into CI framework

Thanks to everyone for their comments.

I will certainly be cautious about any attempt to convert the site and I'll be elisting the help of someone more experience of the MVC approach. I'm thinking that the front of the site is relatively simple compared to the backend so we may be able to re-build that completely in CI and perhaps the backend we can just change bits and host them in a different locations.
