1. How customizable are XenForo's built in SEO friendly Urls? Will I be able to duplicate my current structure so I don't lose indexed pages? Otherwise, are they close enough to something vBSEO may have outputted that a simple .htaccess rewrite line can allow me to keep my current traffic?
2. Does XenForo automatically import user paid subscriptions and user group settings from vBulletin or does this need to be recreated from scratch?
3. There seems to be some bugs on XenForo mobile. When scrolling down a thread, in some browsers you can scroll to the right and find a large open space. Additionally, in some browsers the field for typing the body of your thread does not allow text to be inputted. These issues are fine in Safari and Chrome but I asked my users to test some XenForo sites and see what they think and I guess some less popular browsers cause these issues.
Anyway, hope to get some replies. I still can't get over how fast XF is!
