Acceptance Criteria

The upgrade to PostgreSQL 17.x requires adherence to specific acceptance criteria to ensure a smooth transition and maintain system integrity. The primary criterion is to upgrade the database configuration to PostgreSQL 17.x. The current latest stable minor version is 17.5, but this may change during the release phase. It's crucial to monitor the latest stable release and align the upgrade accordingly. Note that version 18.x is not yet a stable release and should not be considered for this upgrade at this time.

Rigorous Testing Protocols

Successful execution of regression and integration tests is critical. After the upgrade, all regression and integration tests of the product's release candidate must be run using the new database version. This testing phase ensures that the expected functionality and performance remain consistent with the previous version. Testing should be conducted during the milestone release test phase to identify and address any issues early in the process. Compatibility with PostgreSQL extensions must be assessed. If the product uses any PostgreSQL extensions or has specific database configurations, these must be tested for compatibility with version 17.x. Addressing compatibility issues proactively is essential for preventing disruptions post-upgrade. Documenting any upgrade challenges is crucial. If the upgrade cannot be completed within the intended 25.12 release timeframe due to time constraints, identified issues, or functionality problems, it must be thoroughly documented. This documentation should be included in the release check issue and release notes. Furthermore, a plan for completing the upgrade in the next release milestone should be established.

Detailed Testing Requirements

The testing phase is a crucial component of the upgrade process, ensuring that the new database version integrates seamlessly with existing systems and applications. Regression testing involves re-running existing tests to verify that the upgrade has not introduced any new defects or broken any existing functionality. This type of testing ensures that core features continue to operate as expected. Integration testing, on the other hand, focuses on verifying the interaction between different components of the system. This ensures that all parts of the application work together correctly with the new database version. Performance testing is another critical aspect of the testing phase. It involves evaluating the performance of the system under various load conditions to ensure that the upgrade has not negatively impacted response times or throughput. This testing helps identify potential bottlenecks and ensures that the system can handle the expected workload. Compatibility testing specifically targets the interaction between PostgreSQL 17.x and any extensions or custom configurations used by the product. This ensures that all extensions and configurations function correctly with the new database version.

Documenting Upgrade Challenges

In the event that the upgrade to PostgreSQL 17.x cannot be completed within the planned timeframe, thorough documentation is essential. This documentation serves as a valuable resource for future efforts and helps maintain transparency throughout the process. The release check issue should include a detailed explanation of the reasons for the delay. This ensures that all stakeholders are aware of the challenges encountered and the plan for addressing them. The release notes should also contain information about the incomplete upgrade, including the specific issues identified and the steps being taken to resolve them. This transparency helps manage expectations and keeps users informed about the status of the upgrade. A detailed plan for completing the upgrade in the next release milestone should be created. This plan should outline the tasks required, the resources needed, and the timeline for completion. A well-defined plan ensures that the upgrade is completed efficiently and effectively. Thorough documentation of the challenges encountered and the solutions implemented serves as a valuable learning resource for future upgrades. This knowledge helps prevent similar issues from occurring in the future and improves the overall upgrade process.

Upgrade Strategy

The upgrade strategy involves a phased approach to ensure minimal disruption and maximum reliability. The first step is to upgrade the database configuration to PostgreSQL 17.x.
