Cautions¶

• Container Management: When upgrading from v0.21.x to v0.22.0 and higher, if the Global Cluster uses Redis in sentinel mode, you need to change --set global.db.redis.url .
• Global Management: When upgrading from v0.15.x (or lower) to v0.21.0 (or higher), the database connection Helm parameter format needs to be modified. Refer to Offline Upgrade Global Management for details.
• Insight: For Insight Agent versions 0.20.0 and below, there is the problem of collecting multiple copies of JVM metrics data with PodMonitor, requiring modification of the proper configuration. Refer to PodMonitor collects multiple copies of JVM metrics data for details.
• Workbench: When upgrading from versions before v0.21.0 to this version, gitops applications may disappear. It is recommended not to upgrade to this version directly, but to upgrade to v0.22.0 and above.
