Thanks for your replies. I do have quite a few modifications installed, and many other files which are linked by URL, although (I hope) I'll be ok dealing with them one by one so long as the basic site can be moved without too many problems. On reflection, it probably only seems daunting because of my past untidiness. It's definitely time for some "spring cleaning" LOL. I suppose if I'd looked at the files in the original vBulletin installation (as downloaded from vB.com) that would tell me exactly what I need to move . . . doh! After that it will just be a case of addressing any broken links. (I'm getting optimistic now)
I'm currently transferring my board to a new web host. As soon as the migration is complete I'll get started. Thanks again. :up:
