Oracle Database Cloud Migration Professional 2024 ELS — Lesson 1: Migration drivers, source assessment, target services, compatibility, sizing, networking, and method selection

Learning Objectives

• Identify the configuration and data choices that shape Migration drivers, source assessment, target services, compatibility, sizing, networking, and method selection.
• Run normal and boundary tests and record the outcome in migration assessment and method decision matrix.
• Separate root cause from symptom when investigating target sizing based on averages that miss peak workload demand.

Detailed Topics

• Migration drivers
• Source assessment
• Target services
• Compatibility
• Sizing
• Networking
• And method selection
• Decision ownership, prerequisites, and acceptance evidence for Migration drivers, source assessment, target services, compatibility, sizing, networking, and method selection
• Relevant access, data, integration, performance, recovery, and support considerations

Instructor Demonstration

The instructor builds a representative scenario for Migration drivers, source assessment, target services, compatibility, sizing, networking, and method selection, narrating each decision and showing how it contributes to a low-risk database migration to Oracle Cloud with complete assessment, method selection, execution evidence, cutover, and fallback planning. The demonstration records migration assessment and method decision matrix so learners can compare configuration intent with observable behaviour.

Hands-On Exercise

Work through a role-based scenario involving Migration drivers, source assessment, target services, compatibility, sizing, networking, and method selection. Validate the expected path, test the failure case “target sizing based on averages that miss peak workload demand,” choose the safest corrective action, and capture the reasoning and outcome in migration assessment and method decision matrix.

1. Confirm scope, access, sample records, and acceptance criteria.
2. Perform the configuration or transaction using a controlled sequence.
3. Inspect outputs and downstream effects rather than relying on screen messages alone.
4. Close with a support note, preventive action, and reproducible validation step.

Scenario Analysis

• Clarify the business trigger, affected roles, required records, and acceptable result for Migration drivers, source assessment, target services, compatibility, sizing, networking, and method selection.
• Compare at least two implementation or correction choices and identify which evidence would distinguish them.
• Decide how migration assessment and method decision matrix should be reviewed, approved, retained, and handed to the next owner.

Troubleshooting Guidance

Diagnose Migration drivers, source assessment, target services, compatibility, sizing, networking, and method selection by checking effective settings, ownership, source records, dependencies, and recent releases. Use migration assessment and method decision matrix to locate the earliest divergence. Treat “target sizing based on averages that miss peak workload demand” as a hypothesis until the same test passes after correction and still passes for a boundary case.

Validation Checklist

• Configuration and source data used for Migration drivers, source assessment, target services, compatibility, sizing, networking, and method selection are versioned or otherwise traceable.
• Migration assessment and method decision matrix shows both the baseline and the accepted result.
• Security, performance, integration, and operational side effects have been considered where relevant.
• Recovery steps and handover notes are usable by a support practitioner.

Lesson Outcome

Learners can apply Migration drivers, source assessment, target services, compatibility, sizing, networking, and method selection, explain the decisions made, and defend the result with migration assessment and method decision matrix.
