Purpose-Built Data Migration Service
Migrations that follow your exact rules
Move data between systems with complete control over structure, transformation, and governance. Dolphin builds migration tooling to handle complex requirements, edge cases, and rule-driven logic so your data lands exactly as intended.
Purpose-Built Data Migration
Data migrations often involve edge cases, inconsistent structures, and business rules that generic tools cannot handle. Dolphin designs and builds migration solutions that align to how your data works and how you want the final outcome to look.
Why choose Dolphin for migration
A structured, engineering-led approach that prioritises accuracy, control, and predictable outcomes.
We develop migration tools and services designed around your data model, requirements, and edge cases, rather than forcing your scenario into a generic template.
Apply specific conditions, exceptions, and mappings at scale. Rules can be implemented in code, stored in databases, driven by Excel, or combined as needed.
We work closely with your stakeholders to refine requirements, confirm outputs, and deliver a result that matches expectations exactly.
A controlled migration process
Every migration starts with a discovery and planning phase. We review the source and destination, identify dependencies, and confirm the desired target structure, naming conventions, and access model.
We then execute a controlled sample or subset migration. This gives your team the chance to verify the output in a real environment, confirm the rules behave as intended, and request refinements with confidence.
Once approved, we schedule the full migration around your operational needs. Execution includes monitoring, error handling, and clear reporting so you have visibility throughout the cutover.
Discovery & Readiness
Assess the source and destination, dependencies, and risks to build a clear migration plan.
Rules & Mapping Design
Define transformations, naming conventions, routing conditions, and exception handling.
Subset Migration & Sign-Off
Run a pilot migration so stakeholders can validate results before full execution.
Scheduling & Cutover
Plan staged moves and final cutover timing to reduce disruption and downtime.
Post-Migration Assurance
Reconcile results, confirm completeness, and provide reporting and support after go-live.
Governance and assurance built in
Clear visibility, strong controls, and reliable verification throughout the migration lifecycle.
Track what moved, when it moved, and how it was transformed, with logs designed for operational and compliance needs.
Verify counts and completeness across source and destination so results can be confidently confirmed.
Clear documentation of rules, mappings, and execution steps, with a clean handover for future runs if required.
Rules managed your way
Migration requirements often evolve once stakeholders see real outputs. Dolphin designs migrations so rules can be refined without chaos, whether you prefer configuration-driven behaviour or engineered logic for complex scenarios.
Rules can live in the format that best suits your environment. Some migrations benefit from Excel-based mapping tables maintained by subject matter experts, while others require database-stored configuration for controlled updates, or hardcoded logic for speed and strictness.
This approach supports complex conditions and exceptions while keeping the migration understandable, testable, and repeatable.
Excel-driven mappings
Use spreadsheets to control routing, renames, transformations, and lookups without redeploying code.
Database-stored configuration
Centralise rules and mappings for governed updates, versioning, and repeatable runs.
Hardcoded logic when needed
Implement strict or performance-critical rules directly in code for reliability and speed.
Incremental and staged runs
Support phased migrations, delta passes, and controlled cutovers aligned to business schedules.
Clear reporting outputs
Produce actionable reports that show successes, exceptions, and validation results in a client-friendly format.
