Back in SCDF 2.1.x releases, when Undeploying task and redeploying with new version of the application, the schedules actually never gets removed.
Now that we are on a newer version(2.9.x), what is the best way to keep the schedule while doing "task destroy"? If "task destroy" will always remove schedule, is there another way we can upgrade application registration for task without removing task schedules?
