New CMS and URL Structure
 

I have an extensive website - with a related VBulletin forum.

I have already purchased the presale publishing suite and am curious about the CMS. With the new URL Rewriting* is there any possibility of porting over the website to the new CMS system but keeping the EXACT URL structure in place?

Over the years I have done a very successful job with seo and do not want to tamper with my success by redirecting URLs. But the ease of using the CMS appeals to me.

Thanks
