Overview
A maintenance window defines a recurring time slot during which RisingWave Cloud may perform automated operations on your cluster. Currently, the primary automated operation is version upgrades for clusters running deprecated RisingWave versions. When a version you are running reaches end-of-support (see release support policy), RisingWave Cloud will automatically schedule an upgrade to a supported version. The upgrade is executed only during your configured maintenance window.Default maintenance window

How automated upgrades work
When your cluster is running a deprecated version, RisingWave Cloud schedules an upgrade as follows:- Detection — The system identifies clusters running versions below the minimum supported threshold.
- Scheduling — An upgrade plan is created and scheduled for the start of your next maintenance window.
- Execution — During the maintenance window, the upgrade runs. If your cluster is stopped, it is temporarily started for the upgrade and then returned to the stopped state afterward.
- Retry — If an upgrade attempt fails, it is rescheduled for the next maintenance window. Up to 3 attempts are made before the plan is marked as failed and the team is alerted.
- A cluster will not have more than one automated upgrade attempt per calendar week.
- A pre-upgrade backup is taken automatically before the upgrade runs.
- Clusters running pre-release or tagged versions (e.g., release candidates) are not eligible for automated upgrades.
View upcoming and past maintenance
The Maintenance tab shows both the next scheduled upgrade and a log of past maintenance operations. When an upgrade has been scheduled, a banner at the top of the tab shows the upcoming maintenance time and the target version.
