Rolling upgrade limitations

Consider the following points while performing a rolling runtime and an operating system upgrade of a COD cluster.

Operating system upgrade limitations

Rolling OS upgrade is not supported when the COD has edge nodes.
An unwanted rolling OS upgrade can be triggered if a runtime upgrade is not available, resulting in COD downtime. Ensure that the runtime upgrade is available for the selected runtime using the cdp opdb describe-upgrade-database command before using the following command.
cdp opdb upgrade-database --environment <environment-name> --database <database-name> --runtime <runtime-version> --rolling-upgrade
