I have a CMS indergraded with vB forum running on my site. The CMS is the home page and there are about 100+ articles on it. I'm thinking to completely remove the CMS and leave only the forum. The reason for this movement is because I wanna change the default vB skin and the look of the CMS doesn't fit at all.

So, what is the best way to do something like that in SEO prospective?
