    Study Notes

    PostgreSQL Database Migration Example

    • Project: REI's Retail-Stores application PostgreSQL migration
    • Problem: Initial design proposed monolithic migration (moving all data/services at once)
    • Edward's Approach: Hibernate library generated inaccurate/incomplete PostgreSQL schemas.
    • Stakeholder Pressure: Project owner & Scrum Master pressured for fast deployment.

    Pushback Actions

    • Risk Identification: Thoroughly reviewed Edward's schemas, identifying potential Sev1 incidents/data integrity issues.
    • Impact Assessment: Highlighted risks to business operations and customer satisfaction.
    • Constructive Communication: Approached Edward privately to explain issues with his approach.
    • Data-Driven Arguments: Shared results from manual migration scripts, demonstrating accuracy.

    Educating Stakeholders

    • Risk Emphasis: Explained potential dangers of proceeding with untested scripts and damage control necessity.
    • Long-Term Impact: Highlighted potential operational/financial losses with failed migration.

    Alternative Approach

    • Custom Scripts: Proposed custom PostgreSQL scripts for accuracy.
    • Phased Strategy: Suggested smaller, incremental deployment phases for testing and risk minimization.

    Stakeholder Buy-In

    • Collaborative Discussions: Met with stakeholders (Alex, SRE) to explain the phased approach.
    • Proof-of-Concept: Demonstrated script success with local testing.
    • Consensus Building: Highlighted benefits of phased approach to long-term scalability and reliability.

    Implementation

    • Detailed Plan: Created step-by-step plan, outlining resources, timelines, etc.
    • Documentation & Training: Created deployment checklists, rollback procedures (and future migration references).
    • Collaboration: Worked with Alex to prepare for the deployment and Jenkins pipeline.

    Outcome

    • Successful Testing: Local environment testing confirmed 100% data integrity/seamless functionality.
    • Enhanced Team Confidence: Team (Ryan, Vipul, Edward, Douglas) supported the phased approach.
    • Process Improvement: Established a double-verification process and comprehensive documentation. Project on hold (production migration unfinished).

    Challenges and Solutions

    • Resistance to Change: Persuaded team by data/testing.
    • Stakeholder Pressure: Created a thorough plan to reassure them.
    • External Delays: Implemented contingency planning for anticipated delays, avoiding unnecessary risk.

    Stakeholder Convincing

    • Thorough Presentation: Demonstrated risks and benefits of proposed approach.
    • Collaborative Discussions: Engaged with stakeholders, incorporating their feedback.
    • Long-Term Advantages: Highlighted how the phased approach aligned with long-term goals.

    Team Collaboration

    • Clear Role Definitions: Assigned roles based on expertise.
    • Regular Check-Ins: Held weekly sync meetings to track progress and address issues.
    • Collaboration Tools: Used Jira and Confluence to track tasks/maintain transparency.

    Measuring Success

    • Deployment Accuracy: Tracked success of each migration phase regarding schema accuracy.
    • System Performance: Monitored post-migration performance and reliability.
    • Error Reduction: Measured how the phased approach helped diminish critical errors.
    • Team Feedback: Gathered feedback to measure approach effectiveness and improve future migrations.

    Long-Term Maintenance

    • Documentation: Detailed migration documentation to aid in future maintenance.
    • Training: Provided team training for the new environment & best practices.
    • Continuous Monitoring: Implemented monitoring tools for post-migration issue detection.
    • Scheduled Reviews: Scheduled periodic reviews to address any emerging issues or scalability needs.
