Maintenance process
Maintenance is a maintenance service that supports safe and systematic upgrades of OS, engine, and kernel for instances or engines. After a task is created, users can schedule the upgrade at the desired time through schedule settings. If a failure occurs three or more times, schedule rescheduling is temporarily restricted to prevent unnecessary errors. The entire process proceeds in the order of Task creation → Schedule setting → Task execution → Task completion, and overall workflow and progress can be easily checked through resource status values and event lists.
Recommended schedule is provided for reference only. If the user does not set a schedule, the task will not proceed. Make sure to set a reservation schedule.
