Ten year visa

We have a ten year Brazilian visa issued in 2012 in an out of date United States passport. We have new, valid passports but my question is if the visa in my old passport is still valid for entry into Brazil next March (2019). 
Please advise, and thanks

You just bring both passports with you.

Thank you for the fast reply.  Interestingly enough, I came across the answer in an information sheet put out by the Brazilian Consulate of Miami earlier today.  Exactly as you stated, just bring both passports!

Thanks again,
