New US passport, OCI on older passport? - post success stories here

[oktotravel]

guys - my son has his OCI pasted on the old US passport and since he's gotten a new passport, I wanted to check if we really have to go through a re-issue of OCI for new passport. I've heard US customs don't really care and let you through showing OCI on an older passport but trying to get an idea of folks recently doing that and getting through without issues. Can you please post success stories here?

Thx
