Just let me know if we rename a particular host with new name for eg- XXXX is old name and XXXX-PROD is new name and for old name already we have scheduled it for downtime so once we rename what entries we have for old name in downtime will be deleted? And again we have to manually scheduled it with new name? This is how it works?
Yes you would have to re-create the scheduled downtime for the new host, it will not be automatically updated.
