We will need to find a perfect day, it might take 1 to 2 hrs or less depending on how big your forum is.
I had this issue before.
My backup had a drop file and i had to do a lot of recoding to do. I'll be glad to get it up and running again.
If that want you want or ask the vBulletin to do it for you (i think they'll charge you).
