Historical Upgrade Records

Check Items

Check whether the source version of the cluster is earlier than v1.11 and the target version is later than v1.23.

Solution

If the source version of the cluster is earlier than v1.11, it is risky to upgrade the cluster to a version later than v1.23. In this case, contact technical support.
