DigitalOcean fully manages database software updates for database clusters on your behalf. During the update process, we create a new cluster with OS-level or
db_engine updates applied, replicate the existing cluster’s data, and then update DNS (which changes the cluster’s underlying IP address).
There is no downtime associated with these updates, but there may be brief periods of latency during the maintenance window. Updates are necessary for security and stability, so you can’t disable them, but you can customize the maintenance window or manually initiate an available update.
You can view or edit a cluster’s current maintenance window from its Settings page, in the Maintenance Window section.
Software updates may begin at any time in the 4-hour period after the maintenance window’s start time. For example, a maintenance window defined for Sundays at 7pm will have updates at any time between 7pm and 11pm.
To change a cluster’s maintenance window, click Edit.
Choose the day of the week and the start time for the 4-hour maintenance window, then click Save.
When new updates are available, cluster Overview pages have a banner with basic information on the update.
Click Update Now to open the Required maintenance window. This window specifies when the updates will be automatically applied.
If you want to initiate the update immediately ahead of the scheduled maintenance window, click the Start Maintenance button.
