VMware HCX: Deploy, Configure, Manage — Lesson 3: Migration Methods, Network Extension, and Cutover Waves

Learning Objectives

• Reconcile the roles, prerequisites, dependencies, and decision points that shape migration methods, network extension, and cutover waves.
• Design the workflow and produce migration-wave execution log and application cutover evidence that another practitioner can review and repeat.
• Implement “a database tier being cut over before its dependent application tier has completed replication” without introducing an unverified production change.

Detailed Topics

• bulk migration
• live migration
• cold migration
• replication-assisted vMotion
• mobility groups
• dependency sequencing
• network extension
• mobility optimized networking
• cutover runbooks
• application validation and rollback
• Decision ownership and acceptance evidence for migration methods, network extension, and cutover waves
• Relevant security, performance, resilience, rollback, and support considerations

Instructor Demonstration

The instructor demonstrates bulk migration, live migration, cold migration, replication-assisted vMotion, mobility groups, dependency sequencing, network extension, mobility optimized networking, cutover runbooks, application validation and rollback in a representative environment. Each material checkpoint is captured in migration-wave execution log and application cutover evidence, and the walkthrough contrasts the intended state with a condition where a database tier being cut over before its dependent application tier has completed replication.

Hands-On Exercise

Complete a controlled implementation or analysis for Migration Methods, Network Extension, and Cutover Waves. Establish a known baseline, introduce or reproduce “a database tier being cut over before its dependent application tier has completed replication,” isolate the proven cause, apply a reversible correction, and record the accepted result in migration-wave execution log and application cutover evidence.

1. Confirm scope, identities, infrastructure, dependencies, and expected result.
2. Execute the planned configuration or operational sequence while preserving checkpoints.
3. Test one expected path, one boundary condition, and the identified failure path.
4. Retest after correction and document rollback, ownership, and preventive action.

Scenario Analysis

• Decide which requirement or dependency has the greatest influence on migration methods, network extension, and cutover waves.
• Compare two valid implementation or recovery choices and identify the evidence that would distinguish them.
• Explain how migration-wave execution log and application cutover evidence should be reviewed, retained, and handed to the next owner.

Troubleshooting Guidance

Begin with effective configuration, recent changes, connectivity, health, logs, and timing. Use migration-wave execution log and application cutover evidence to find the earliest divergence between expected and observed behavior. Treat “a database tier being cut over before its dependent application tier has completed replication” as a hypothesis until the corrected path passes both the original test and a boundary condition.

Validation Checklist

• The implemented state for migration methods, network extension, and cutover waves is traceable to approved inputs.
• Migration-wave execution log and application cutover evidence contains baseline, test, correction, and accepted-result evidence.
• Security, capacity, performance, resilience, downstream impact, and rollback were considered where relevant.
• Monitoring, escalation, recovery, and support ownership are clear enough for operational use.

Lesson Outcome

Learners can apply Migration Methods, Network Extension, and Cutover Waves, explain the decisions made, and defend the result with migration-wave execution log and application cutover evidence.
