Loading old songs , vst presets embedded in file?

I,ve got some old renoise files and upon loading it can’t find the vst instrument whcih is pretty obvious since I 've changed computers a couple of times .
But, since I still have the vst plugins I can easily reload them but as a result the preset is mising .
So , is it possible to open up the renoise file and extract the appropriate data from the file , assumming the vst preset is embedded within the file ?
Anyone had any succes doing this ?
