CDJ 350

Hello :) I have to use CDJ 350's in Sifnos Greece to DJ a wedding, as that's all they have available! They do not have anything more current. <FYI: I'm used to Pioneer CDJ 3000's or the the XDJ RX3> I have a Rekordbox subscription and old Serato software. Which software can I use with the CDJ 350 with my laptop? Or is it better to export my music in Rekordbox onto USB's? I'm going blindly into using the CDJ 350's so any help would be much appreciated!
