Upgrade Considerations¶

• Microservice Engine: When upgrading Microservice Engine to a version greater than v0.24.2, there are incompatible updates for versions up to v0.24.2. Since the gateway involves changes in the URL of the open-source component repository, you need to manually delete the existing gateway-api-admission-xxxxx Job before performing the normal upgrade process.
• Global Management: When upgrading from v0.15.x (or lower) to v0.20.0 (or higher), the database connection Helm parameters format need to be modified. For more details, refer to Offline Upgrade of Global Management.
