Transfer from industrial trainee

Hi people,

I have been shifted to industrial trainee from article ship during last year of my tenure. I have called up ICAI customer care if i can take transfer to another CA firm and not any industry. I have been told by them that i can do so, however my period of internship in industrial training shall be null and void. 

I have no issues with that but just want to get this thing re-confirmed, as you know how those customer care people in ICAI are.

Thanks & Regards
