I am looking to move my vbulletin to a new host, along with getting the forums their own domain name, instead of a subdomain. Is it possible to move the bulletin without losing all of the posts, etc? If so, is it a difficult process? And lastly, is there some documentation somewhere as to how to do this?

Thanks in advance

u need to backup the database file and ur forums files and everything u have.After that u load in to ur new database.It should be working.I did the same things for my forum shifting too. ^^

Jelsoft wrote a good bit of documentation:

I have done this 4 times and it went smoothly. Slow, but smoothly!
