Installation / conversion

I have a vBulletin 3.8 board (about 20K messages), using vbseo.

A couple of questions before I place my order for xenForo:

(1) Does your installation service include the vBulletin conversion?

(2) Does the installation service include the redirection scripts? I've read the messages in your support forums about the vbulletin & vbseo redirection scripts, but it's unclear to me whether I need both of them or just the vbseo. And I'd really rather have somebody who knew what they were doing install that part! :)

Thanks for your help.
