Question - Possible get a developed old app to Google Play? What to change? (opens in new tab)

Hi. Managed to develop a new version of RoboCam from Proghouse and develop it some for new versions of Android versions. I want to upload it to Google Play but what do I need to change to be able to get it accepted and not be blocked as a copy? I managed to add Huawei 360 camera as a option...
