Should I submit a new item or update the current item?

I’ve recently uploaded a WordPress plugin that was approved. It has no sales at the moment. I’ve decided to divide the plugin into a Free + Premium extension, and reduce the price. I’ve uploaded the free version on, and wondering if I should simply update the current item on codecanyon using the premium extension, or should I delete the current item and uploaded a new one.

I’m splitting a Premium plugin into Free + Premium extension. Should I resubmit it or edit the current item and replace?

Thanks in advance.

I would update the existing one - there is a danger that the other route would not be approved
