Upgrading Legacy Cobol

I keep reading about how much Cobol code is still in production. And the main reason it has not been updated to a more modern language is because it is too long or too expensive.

My question is: if there was a tool that converted Cobol, say, to Java, would any organizations be useful? Or would they rather continue to support what they already know?

Currently, a large amount of COBOL code (I would rate more than 90%) is not tested.
