Migration from vBullitien 3.6.8 to Xenforo


I have a huge forum running on vBullitien 3.6.8 and am very interested in migrating to Xenforo.
My primary concerns are:

1. I am using SEF urls in my current vBullitien forum. Will i be able to migrate all data and maintain the url structure on Xenforo as i dont want to loose on content and traffic? Are there any tools available to help for data migration? My current URL structure in vBullitien is - http://www.4x4earth.com.au/forum/remember-me/27587-farewell-old-friend.html
Will i be able to maintain the same url structure in Xenforo

2. I want to source images from Microfost Azure or any other server and not keep them on my server. Are there any add-ons available to help with this?

Can you please provide me input on these 2 points and i'm eager to port to xenforo if my concerns can be handled.
