You might take a shift from main campus to any other campus but from other campuses to main campus, that’s indeed a problem.
Maintain a cgpa of 9.5+ and you need to get permission from your hod, registrar, director and many other people. It’s not easy at all. You might just have 0.00001% chance to make it. I have never heard of someone do that but for the time being, ask your faculty advisor and hod.
All the best.
