Can an IG cassette be replaced with a HG cassett, if you also change to a HG chain?
If you can, does the front chain rings have to be replaced also?

IG and HG use the same cog spacings (given the same number of cogs, I mean). I use SACHS chains with both, since I find they have good reliability compared to the Shimano chains I've used. Whether your chainrings will need replacement depends on how worn they & the old chain have become.
