Hi @krishbs
A new PERM and i140 would be required for a new ‘job position’ that you are working in after your promotion if you want to use this same position to file i485 green card later.
You can use the existing i140 to port your PD date.
If you are from India, you can skip filing the new PERM and i140 at this time and do it as and when your PD date is close to getting current.
