Don Mueang international airport immigration

I’m flying from Phuket to Bangalore (India, home country) with a layover and flight change in DMK. I land in DMK T2 and have my next flight from T1. However I have only 90mins between my flights during which I’ll have to get to T1, complete immigration and get to the gate. I have no check in luggage. Was wondering how long immigration takes in DMK T1 and if I can make it in time. Anyone with any idea please help here.
