0.7 and 0.8 have mostly the same package/class names, so you have to shade one of the jars if you want them to both be loaded and executable in the same jvm process. I've done this in my consumers (e.g. my consumers consume from both 0.7 and 0.8 during the transition). I chose to run separate kafka instances for 0.7 and 0.8, and not attempt to do any forwarding from 0.7 to 0.8 during the migration.
