Granted Visa by Officer, had a damaged photo in the passport, so he asked me to submit the new passport

The VO asked me proper questions, he said i have got the visa, but i would have to submit a new passport at the OFC place and said that the visa would be issued on that. He gave me a white form and ticked the check box of the passport submission option. Is it assured that i will get the visa?

There is never a guarantee. However, if he said that visa is approved, you can expect the positive outcome.
