If I understand your question, you just want to "clone" your production installation of UBB.threads 6.1? Here are some notes I wrote up. This is for 6.2 on Linux, and uses shell commands, but it may be helpful.

----------

Cloning a test copy of a UBB.threads installation

Source board:
MySQL database name - foo_db
MySQL user - foo_user
install dir - /example/htdocs/ubbt/foo_dir
non-HTTP dir - /example/ubbt/foo_dir
admin/MySQL log dir - /example/ubbt/foo_dir/logs
cookie prefix - 1

Target board:
database name - foo2_db
MySQL user - foo_user
install dir - /example/htdocs/ubbt/foo2_dir
non-HTTP dir - /example/ubbt/foo2_dir
admin/MySQL log dir - /example/ubbt/foo2_dir/logs
cookie prefix - 2

1) Copy the database foo_db to the database foo2_db.

The easiest way is probably to use mysqldump to back up foo_db, and then restore the backup into foo2_db.

First create the database foo2_db, and if necessary, adjust foo_user's grants so that it has access to foo2_db.

Then:

mysqldump --quick --add-drop-table --add-locks --lock-tables -ufoo_user -p foo_db >foo_db.sql

mysql -ufoo_user -p foo_db < foo_db.sql

2) Create the clone directories, and copy all files from the source directories to the target directories.

mkdir /example/htdocs/ubbt/foo2_dir
mkdir /example/ubbt/foo2_dir

cp -a /example/htdocs/ubbt/foo_dir/* /example/htdocs/ubbt/foo2_dir
cp -a /example/ubbt/foo_dir/* /example/ubbt/foo2_dir

(Ensure that hidden files such as .htaccess were copied.)

3) Edit the configuration files to change the references.

Change all occurrences of "foo" to "foo2" in the following files:

/example/htdocs/ubbt/foo2_dir/main.inc.php
/example/ubbt/foo2_dir/config.inc.php

Edit /example/ubbt/foo2_dir/config.inc.php and change $config['cookieprefix'] from "1" to "2".

4) Delete the copied log files.

rm /example/ubbt/foo2_dir/logs/*

That's it.
