Serato DJ Pro issues

hi guys I wonder if I could get some advice. I use an old version of Serato DJ Pro which I’ve never changed for my Pioneer DJSX. It works fine and I don’t intend to update the Serato DJ pro.

I’ve just purchased as a backup a Hercules starlight please can you tell me if this will work with an old version of Serato DJ Pro? As when I plug it in it does not recognise the laptop although it does power on.

Does this mean I have to use the Hercules with Serato DJ Light? If I do, will it recognise my folders and crates that the SeratoDJ Pro uses? As would hope that it does.

Please can you advise

thank you very much
