Mapping genome positions between different WS releases

Dear all,
is there any standard way or recommended approach (I wouldn’t mind if it requires a bit of scripting) to convert genome positions between different WS releases?
I’m mostly interested in a conversion between WS220 and 235, but a general solution would be great of course.
Thanks for any feedback,

I think there was a page on the old WormBase wiki :
Mostly GFF based, but it should work.

Thanks a real lot for the link!
Converting my data to gff should be straightforward, so it looks like this does exactly what I want.
Have a nice weekend,
