CPANEL, ENGINEER,WEB HOSTING,

Hi, i bought an Application that was already in (ios) App Store and (Android) Google Play and asked that the name be changed but after the name changed, i received below message from the App developers who are working on it. """"So - domain is managed by Google now, which is good. But - In a few days I'll need to redirect [login to view URL] to appengine. Which means that [login to view URL] will stop working. I'm sorry but I don't know how to do this correctly. Do you have any technical person who can advice me on this?""""" I need someone to help my App developer solve the Cpanel problem. thanks.
