All that you need to do is open the image with an interpreter VM and save it. It will be saved in the format that can be used by an older VM (i.e. format 6504) and can of course still be opened with Cog. If you are building image with Jenkins, just add a post-processing step to re-save the final image using an interpreter VM. Dave
