is this possible to convert from biblatex to bibtex format

Question

My code are follows:

\documentclass{book}

\usepackage[backend=bibtex,sorting=ynt,
 citestyle=numeric,
 bibstyle=numeric,
 maxnames=3,maxbibnames=99,
 sortcites,
 url=false,
 mincrossrefs=50
]{biblatex}

\bibliography{test}

\begin{document}

\cite{lustrec,eis07,DBLP:journals/corr/GarocheGK14,DBLP:conf/nfm/GarocheHKT14,Motzkin}

\printbibliography


\end{document}

Using biblatex everything working fine, my concern is is it possible to convert the same from biblatex format to normal bibtex format?
