Hi Mauricio, Thank you for the update regarding the rollout, When you say the
tasks continued running uninterrupted through the executor procedure, does it
mean the existing tasks are still running with the old version of the
executors? As that process did not exit during the upgrade.
Would appreciate your clarification on the above.
ThanksRaghu

Hi,
I updated the executors and then rolled the schedulers (have 5 of them).
Everything went smooth, and the tasks kept running :)
