I don't think the 0.7 -> 0.9 upgrade path has been tested. I think it is advisable to upgrade from 0.7 to 0.8 then later upgrade from 0.8 to 0.9. I think Jeff's upgrade steps are reasonable and shouldn't give you any trouble. Note that upgrading the executors won't affect existing tasks. If you want the current tasks on the system to adopt the latest executor you will need to upgrade the executor and then roll your tasks so they can be relaunched with the updated binary. This isn't necessary to do but keep this in mind if you are expecting tasks to leverage the latest executor functionality.
