Metarea 1960 News?


I think my question has been asked before but I couldn’t really get the answer I was looking for. So I’m sorry if the question is redundant.

I know there has been an updated 1960 US Census version available. However, the METAREA is in all cases “not identified”. Is there a way to convert/cross-walk the MINI-Puma or another geographic variable to the METAREA variable?
