Do I need VISA to avail the conneting flight from SHA?

Hi,
I am going visit South Korea on Jan 16, 2015. I am an Indian citizen. I do have my South Korea tourist VISA. While returning back to India on 26th January, there is airport change in Shanghai. i.e. Pu Dong to Hongqiao.

I will reach at Pu Dong - PVG airport around 10:00 hrs from Seoul by China Eastern and I will have flight (same carrier - China Eastern) to India from Hongqiao - SHA airport at 16:10 hrs on same day.

Seoul (ICN) -> Pu Dong (PVG) -> Hongqiao (SHA) -> Kunming (KMG) -> Kolkata (CCU)


So there is around 5-6 hrs time difference. I have to come out from Pu Dong (PVG) airport and I will go to Hongqiao (SHA) airport to catch my China Eastern flight to India.

For this do I need any transit visa or I will get some temporary stay permit in Pu Dong airport.

Please confirm as soon as possible. Thank you and look forward for your utmost co-operation in this regards.
