The best way how to achieve eps to cdr conversion, i.e. convert Encapsulated PostScript (.eps) to CorelDraw drawing (.cdr) is to of course use CorelDraw as it support both these file types just fine.
Considering that Corel's CDR format is proprietary, using 3rd party software or some web-based eps to cdr converter online may not create the latest version of CDR format, but one of the previously used ones, which could cause you compatibility issues later. However, we do not know about any desktop / online tool that can convert eps to cdr, except CorelDraw.
