This lesson develops practical capability in Migration Assessment, Compatibility, Data Transfer, Testing, Cutover, and Rollback as part of DP-3021 – Configure and Migrate to Azure Database for PostgreSQL. Learners connect the concepts to a realistic workplace objective, perform guided work, validate evidence, and document improvements.
The lesson begins by defining the architecture, stakeholders, information flow, operating assumptions, and quality expectations that shape migration assessment, compatibility, data transfer, testing, cutover, and rollback. It distinguishes essential decisions from optional enhancements and explains how security, governance, usability, cost, and supportability influence the final design.
Learners then map the end-to-end workflow, identify control points, and choose appropriate configuration or analysis steps. Special attention is given to dependencies, permissions, data boundaries, exception handling, documentation, and the evidence required for an accountable operational handoff.
Apply the lesson to a scenario in which an organization must improve configuring and migrating workloads to Azure Database for PostgreSQL through service planning, deployment, networking, identity, security, migration assessment, data transfer, cutover, performance, high availability, backup, monitoring, troubleshooting, and validation. Produce a concise plan, implementation or analysis evidence, a validation checklist, a troubleshooting record, and a prioritized recommendation for the next iteration.
