Surrender old cancelled passport too?

[elvampiro]

Hi

While surrendering Indian passport for OCI, should I also turn in my old cancelled passport?
Or is it just the latest Indian one alone that I need to surrender?

My old (CANCELLED) one has a lot of visas and stampings that I want to keep as a souvenir of my travels , do I need to turn it in, or can I keep it?

Also, what happens to the recent one? Do they take it away of just stamp CANCELLED?

Cancelled passports are not required for surrender.
They returned my current passport as well with Surrender Certificate after cancelling it.
