Articleship Issue

Sir,I had started my articleship training on 21/09/2015. I am still working there. But due to issue I want to take transfer. However I have crossed 1 year of articleship. Can I take backdated transfer?
And since 1 month have crossed, will ICAI object in giving transfer. Will I also have to ask for permission from ICAI through letter for taking a transfer? As this will take lot of time. Please suggest me at the earliest.
