Cpt - ipcc - articleship

I have cleared my CPT exam in June 2010 and for some reasons i have not written IPCC exams. But now I understand that the course structure is changed and we can register for articleship without having written IPCC exams.

Can you please let me know if I can join articleship now under any CA and start writing IPCC exams as well?

Now CPT is not mandatory for graduates with 55% marks but I had cleared CPT under old pattern in 2010 and was registered for IPCC in 2010 itself.

Please advise whether i am eligible for articleship registration and IPCC exams writing under the same registration that I have for IPCC or do I need to get re-registered under new scheme and then join articleship without appearing IPCC exam.
