Transit visa requirement from T1 to T2 at Guangzhou Baiyun Airport

Hi

I'm travelling from India to GZ via Indigo airlines (arrival at T1)

Then I'll be changing the terminal from T1 to T2 to board China southern flight to cebu (Phillipines)
Layover at Guangzhou for terminal change is for 6 hours.

Can you please help me that will I need a transit visa?
