Upgrade Considerations¶

• Container Management: When upgrading from v0.21.x to v0.22.0 or later, if the Global cluster is using Redis in sentinel mode, the --set global.db.redis.url needs to be modified during the upgrade.
• Global Management: When upgrading from v0.15.x (or lower) to v0.21.0 (or later), the format of the database connection Helm parameter needs to be modified. Refer to the offline upgrade for global management for more details.
• Insight: For Insight Agent versions 0.20.0 and below, there is a known issue with collecting multiple JVM metric data using PodMonitor. Configuration changes are required. Refer to the PodMonitor collects multiple JVM metric data for more information.
