1. Purchase XenForo
2. Install XenForo
3. Install portal add-on (for CMS like funtionallity)
4. Import vB data (users/threads/posts/PMs/etc)
5. Install redirect scripts to maintain SEO?
Number 5 is the one I'm most uncertain about. I want to minimize impacts on search rankings. I'd like to install xenForo in a different directory than the current vB install if that won't complicate it.
Are there any steps I'm missing?
