Here's what to do..

Upload the old sql file to a directory on your server (preferably outside the web directories - for security reasons)

Create a new, blank database or clear out an existing one.

Go into SSH and type the following command

mysql -u [mysql username] -p [.sql filename] > [name of database you created/cleared]

This restores the contents of the SQL file into the database.

Now download vb3, edit the file at includes/config.php, upload everything into your web directory and run the upgrade script, this will convert your forums to vb3.
