Can I rename a Java keystore file through Windows/Eclipse without having to regenerate it?

We're rebranding our product and as a part of that we need to rename a keystore used by Java for secure XMLRPC connections between our components from OLDBRANDNAME_keystore to NEWBRANDNAME_keystore. Can we safely do this simply by renaming the file using Windows or Eclipse and updating the references wherever it's used or do we need to completely regenerate it and all the certificates within? I've tried Googling this but I can only find references to updating internal entries.
