Any way to match the deprecated api's post ids to the new api's post ids?

Looks like we have different insta user ids and post ids. The post id is very similar to the id that is stored under "data"."caption".".id". but it's still not the same id. For example it's off by 1 digit or so everytime.

Old post id: "178911639 23 515387" new post id: "178911639 20 515387"

I changed some of the numbers, but you can see it's just that inner digit that is different. Seems oddly suspicious. Regardless, I wish we could match id's across APIs.

Anyone have any ideas?
