PMSS:Transferring user from another system
From Pulsed Media Wiki
This is kind of easy, but requires a follow up checkup.
Login to the server you need to transfer data to, and do:
cd /scripts/util screen ./userTransfer.php LOCAL_USERNAME REMOTE_USERNAME SERVERNAME
After you see transfer begins, press ctrl+a c to create new window to keep user data private even from your eyes. You can go back to previous window doing ctrl+a p and then clear text by ctrl+l. See Using SCREEN
After completion restart user rTorrent. You might want to also verify permissions.
