What you can do is create each user in the control panel.
There is a tab in the members section called add new member
Then there is a button to email the password you entered for them and then they can change the password after the first login.

If you wish to go farther you can in member search select the user you added and use the become member and copy posts from the old forum to the new forum as them.
Then just logout.

Now you will need to build the forums so they match your old one

There is no such thing as stupid questions. Just stupid answers
