First, I'm not asking how to do this. I am asking which might be the best way. I have a VM with two different versions of the same OS on one VDI. I don't need one of them. My question is, would it be better to just use something like gparted and delete the partitions of the one I don't want then resize the one I do? Or, can I clone, copy, move just the one I want to a new VDI?

thanks.
