since 2008 it is long time . u need to check with DGCA , if they have trashed your PMR u need to do class 2 again and thereafter class 1.
you need to write later to DGCA mentioning your case . if you are granted NOC
directly for class 1 well and gud.
smimilar was case of my friend his last medical class1 was in 2008 and he renewed this year. he was mentioned on letter to do class 2 again and once its updated he can apply for class 1. his file no was kept same .
