Migration Services

Move your database without breaking production.

The Database Ninja team plans and executes database migrations with zero or near-zero downtime. Version upgrades, cross-engine moves, cloud migrations, and consolidation projects. Every migration includes a tested rollback plan and a production dry run.

Overview

Migrations done right, the first time.

Database migrations fail for predictable reasons. Teams underestimate the complexity of replicated systems, assume incorrect encoding behavior, skip pre-migration data quality checks, or run the cutover without rehearsing it under realistic load. The Database Ninja team has done enough migrations to know exactly where the traps are.

We handle major version upgrades (Oracle 19c to 26ai, PostgreSQL 12 to 17, SQL Server 2016 to 2022), cross-engine migrations (SQL Server to PostgreSQL, Oracle to PostgreSQL), cloud migrations (on-premise to OCI, AWS, Azure, or GCP), and consolidation projects (many small instances into fewer larger ones).

Every engagement includes pre-migration data profiling, schema conversion where applicable, a full production-scale rehearsal in a non-production environment, cutover orchestration, and post-migration validation. We stay on call for the first week after go-live.

What's Included

The migration playbook.

Discovery and Profiling

Complete audit of your current schema, data volumes, dependencies, and workload patterns before we touch anything.

Schema Conversion

For cross-engine moves, we handle syntax differences, type mapping, constraint preservation, and stored procedure translation.

Data Movement Strategy

Initial load plus incremental sync using GoldenGate, logical replication, DMS, or custom change data capture depending on the platform.

Cutover Rehearsal

Full production dress rehearsal in a non-production environment with realistic load and timing. No surprises on go-live day.

Rollback Plan

Every step has a tested reverse. If the cutover fails, we can walk it back to the original system within minutes.

Post-Migration Validation

Row counts, checksums, application smoke tests, performance baselines. We prove the new environment matches the old before we close the engagement.

Why Database Ninja

Why migration projects succeed with us.

We rehearse everything

Every migration gets a full production-scale rehearsal. We find the problems in the lab, not on cutover night.

We write the rollback first

Before we build the migration path forward, we build the path back. Every step is reversible until the moment we commit.

We stay after go-live

Our engineers stay on call for the first week. If something goes wrong, the people who built the migration are the ones who fix it.
