When you utilize the importer to import UBB.Classic to UBB.threads you'll want to edit the classic_import.php file and change:
Code
$site_id = 1;

To read 2, this should import all data as a separate set of data (I'd test it first, as a dry run). Please note that you'll likely end up with a ton of duplicate users that you'll want to merge once imported into UBB.threads.
