Hey Winner ,
Well i believe that first you need to get your self a JAA CPL-IR license with MCC course . then you need to stamp the type rating on your JAA license . now since you are already rated on that bird you just need to check if the training center where you did the type rating a JAA approved training center or not , if yes you just need to do a proficiency check with a JAA examiner and then you can stamp it on your new license. if the place where you did the type rating is NOT JAA approved you will have to do a new one according to JAA regulations
i hope that would help .
