I have running a forum Threads 6.5.1 like this http://forum.domainname.com
It comming directly out in de root of the forum (so in the ubbt dir) E:\content\forum\www\ubbt

What is the best way to import the new forum?

Must I set it back the url http://forum.domainname.com back befor the ubbt dir with a redirect script to the old forum?

Must I make a new dir ubbtthreads and make a compleet new running forum and import the data form the importers directory?

Must I also kopie the upload files in the new directory?

The first place to look for import instructions is: http://www.ubbcentral.com/doc_import.php

Yes I have read it, but I just wondering that I must install ubbthreads in the same directory or another?

UBB.threads 7.0 is a differant product than both UBB.threads 6 and UBB.Classic 6 and should be treated as such, first installing to its own directory, then imported; then later changing the directory shoudl you wish to do so.

When I import the old forum it stops on:
http://www.domainname.com/ubbthreads/importers/threads_import.php?ubb=posts&start=780

And have this message:

No input file specified.

What to do now is this a bug?
