I've a database of a SMF Board and I've installed in my joomla a SMF board... and I don't know how to import a database of smf to joomla databse with other sufix... in joomla have "_jos" and the smf "_smf".
Well if you did a fresh install of SMF you just put in the database name, path, username and password to the Joomla Database once the install is complete of SMF the two are using the same database
