Database Migration Presentation Template

Database migrations are among the highest-risk engineering changes an organization can undertake. They touch data — the one thing that cannot be reconstructed if something goes wrong. A clear, thorough migration presentation builds stakeholder confidence, surfaces risks before they become production incidents, and documents the plan in a format everyone can review.

Who Needs to See a Database Migration Presentation

The audience for a database migration presentation is typically broader than for most engineering decisions. Engineering leadership needs to review the technical plan. Product stakeholders need to understand the user impact and timeline. Operations or SRE teams need to review the rollout and rollback plan. Legal or compliance may need to confirm data handling meets regulatory requirements.

Build the presentation to answer all of these audiences — start with the business impact, then go progressively deeper into the technical plan.

Slide-by-Slide Template

Slide 1: Migration Overview

What is being migrated, from what to what, and why. Name the source and target — whether that is a different database engine (MySQL to PostgreSQL), a version upgrade (Postgres 14 to 16), a hosting change (self-hosted to managed), or a schema restructure. State the business reason for the migration in one sentence.

Slide 2: Business Case and Drivers

Why this migration is happening now. Common drivers: a version reaching end of life with no security patches, performance constraints hitting the current database that the new system resolves, cost reduction from moving to a managed service, or architectural requirements of a new product capability. Quantify the driver where possible — "version 11 reaches end of life in [month] and will receive no further security patches" is more compelling than "we need to upgrade."

Slide 3: Scope

What data is being migrated, the approximate size of the dataset, the number of tables or schemas involved, and the services or applications that connect to the database. Show a simple diagram of the services that will be affected by the migration. This gives stakeholders a sense of the blast radius.

Slide 4: Risk Assessment

A table of migration risks with likelihood and impact ratings, and the mitigation for each. Common risks to document: data loss during migration, data corruption, extended downtime, application compatibility issues with the new database, and performance regression. Do not omit risks to appear more confident — a risk that is named and mitigated is less alarming than one that appears during the migration.

Slide 5: Migration Strategy

The technical approach — live migration with replication, dump-and-restore, blue-green database switch, or phased migration service by service. Explain the strategy in plain terms and why it was chosen over alternatives. If the approach requires downtime, state the expected downtime window explicitly.

Slide 6: Testing Plan

How the migration will be tested before the production cutover. This should include: a test migration against a production-sized data copy, application testing against the new database, performance benchmark comparison between old and new, and any automated data validation that confirms row counts and data integrity.

Slide 7: Rollout Plan

Step-by-step production rollout sequence. Who does what, in what order, and at what times. Include the go/no-go criteria at each step — the specific conditions that must be true before proceeding to the next phase. A rollout plan without go/no-go criteria is just a wishlist.

Slide 8: Rollback Plan

What happens if the migration fails. The rollback plan should be as specific as the rollout plan: at what point in the process can you still roll back, what the rollback steps are, how long rollback takes, and what state the data will be in after a rollback. If rollback becomes impossible after a certain point, state that explicitly and explain why.

Slide 9: Communication Plan

Who will be notified about the migration, when, and through what channels. Scheduled maintenance windows, customer-facing notifications, internal status page updates. For migrations requiring user-visible downtime, show the customer communication draft or schedule.

Slide 10: Timeline

The planned timeline from current state to completion. Include preparation phases, testing milestones, the production cutover window, and the post-migration stabilization period. Mark any hard deadlines — compliance dates, end-of-support dates, dependency milestones — that constrain the timeline.

Slide 11: Sign-Off Requirements

Who needs to approve the migration before it proceeds. List the approvers, what they are approving (technical plan, business risk, communication plan), and the deadline for approval. Clear sign-off requirements prevent the migration from starting before everyone is aligned.
