I am currently trying to transfer too. My story isn`t the nicest tho: I met one guess speaker at my currently university and just loved his work. My lab is stacked in old technologies and I feel we arent innovative at all. I talked with this guess speaker and her answer was very positive regarding getting me as her student. However she asked me to tell my supervisor before applying: bad idea. Maybe because I am in Asia and here the culture is that your professor is a God, he was really unpleasant and rude with me. He even said he would write bad recommendation letters for me if I change universities. For me that was harassment. His main reason was the money invested and how bad this looks for him and for the university. My advise is: be sure you can move and then talk with your adviser. The only positive thing was that after talking with him, I was certain that I am at the wrong place. I am positive I can change, so if you arent happy or the program isnt align with your future goals and perspectives, change! Dont waste your time.
