Lifetime validity is only given to those who have an RTR A after passing both part 1 and part 2 and paying 10,000 rupees
Converted RTR licenses like RTR P & C max validity is 20 years ( depending upon the foreign license )
And RTR P is given on the basis of both FOREIGN FRTOL and FOREIGN CPL
You dont need to give part 1 again
Just go and apply for a fresh RTR P license instead of a renewal
If your foreign FRTOL has lifetime validity then you can pass part 1 and aply for an RTR C which will be issued for 20 years
And congrats to all those that passed the Delhi attempt
