transfer students?

[unhappy phd]

Hi all,

Just wondering if anybody have any experience in transferring...I am a first year and am unhappy with my current phd institution (personal reasons) and would like to transfer to another school. I was also accepted to this other school that I would like to transfer into last year and I read online that they accept transfer student. Since their application deadline is next week...should I just contact the graduate school dean directly? I am really hesitant to send that email 

Any input is welcomed!
