Batch Convert from .wps to .doc or docx

I have been seeking a way to batch convert WordPerfect files to the .doc
format. I was reading that this could previously be done on some versions of
Libreoffice. There was something about a command line where this could be
done. I have been unable to find any information regarding this in the
current version.

Is there still a way that batch conversions can be done in Libreoffice? If
so can anyone help?

WordPerferct is the preferred program to convert its own file format to
.doc. Nothing qualifies LibreOffice to convert from one foreign file
format into another foreign file format. Even though this is possible,
the results may be far from "Word Perfect".
