Old or new itt and orientation programme

Hello,

Please help me with confusion regarding ITT and Orientation programme whether I should do Old one or New one.

I have registered for IPCC under Direct Entry Scheme on  26/05/2016.

But due to some reason, I was not able to continue the course. at that time requirement for appearing in IPCC Exam are  ITT and Orientation programme and 9 months of practical training. I have not registered for both programmes.

but now I want to continue the course and the revised scheme is implemented on 1/7/2017.

So my confusion is that what programme I need to complete OLD or New(ICITTS) or I need to take fresh registration.
