Need NOC for two wheeler to transfer RC to Karnataka

I have moved to Bangalore and need to get an NOC for my two wheeler from Coimbatore to get my RC transferred. I have filled out the form on Parivahan website and submitted the required document. Now the system is asking to book an appointmnet and visit the RTO. Can anyone tell me what are the next steps. What document I need to carry? Can anyone else represent me at the rto?
