Upgrade Considerations¶

• Microservice Engine: When upgrading from a version greater than v0.24.2 of Microservice Engine, there is an incompatible update regarding the gateway due to changes in the open-source component repository. Therefore, before upgrading, manually delete the old gateway-api-admission-xxxxx Job and then proceed with the normal upgrade process.
• Global Management: When upgrading from v0.15.x (or lower) to v0.19.0 (or higher) of Global Management, the database connection Helm parameter format needs to be modified. For details, refer to Offline Upgrade of Global Management.
