vB 4.0 upgrade to CMS - will it still preserve URL structure?

So I am a long time user of vBSEO and have multiple licenses for the pre-vB 4 versions. Now that vB 4 is working out some of the bugs, I'm considering upgrading soon, but have a a concern regarding the content management system:

With vB 3.x, of course the forum home is simply the forum directory. For my sites, I have that set for the URL's index.php. Now let's say I upgrade to the 4.0 w/ CMS and I want my home page to look like this:

Can I do that and still preserve the URL structure of the forums and posts on the site, yet still have the CMS homepage?

Yes, the only thing that is changing is the actual forumhome script. The rest of your forumdisplay and showthread urls will not be changed.
