Legacy Modernization · Data Migration

Move decades of data without losing a single record.

Your legacy system holds 10, 20, even 30 years of data -- customer records, order history, pricing tables, inventory transactions. We migrate all of it with format conversion, cleansing, deduplication, and validation. Every record accounted for.

The Problem

Data Migration Is Where Modernizations Silently Fail

Legacy data formats don\'t match modern system structures -- field mappings are ambiguous and lossy
Decades of data quality issues surface during migration -- duplicates, orphans, invalid formats, missing fields
Historical data that seems unimportant turns out to be critical for compliance, reporting, or customer service
Data migration tested with samples passes, but full-volume migration reveals edge cases that break everything
What We Deliver

Service Scope

01
Data Profiling

Analyze every table, field, and relationship in your legacy data. Identify quality issues, data volumes, format inconsistencies, and transformation requirements before migration begins.

02
Mapping & Transformation

Define field-by-field mappings between legacy and target systems. Handle format conversions, code translations, concatenations, and business rule transformations.

03
Data Cleansing

Fix quality issues during migration -- standardize addresses, deduplicate customers, resolve orphaned records, and fill missing required fields with governed defaults.

04
Validation Framework

Automated record counts, checksum validation, and business rule verification. Every record is accounted for -- nothing lost, nothing corrupted.

05
Incremental Migration

Migrate historical data in advance, then incrementally sync changes during the transition period. Minimize cutover window and reduce go-live risk.

06
Rollback Capability

Full rollback capability at every stage. If validation fails, revert and fix without impacting the legacy system or losing data.

How We Work

Engagement Process

01
Data Profiling

Analyze source data volumes, quality, formats, and relationships. Produce a data quality report with issues ranked by severity and migration impact.

02
Mapping Design

Design field-by-field mappings with transformation rules. Review with business stakeholders to validate that mappings preserve business meaning.

03
ETL Development

Build extraction, transformation, and loading pipelines. Automated, repeatable, and version-controlled -- not manual copy-paste.

04
Test Migration

Run full-volume test migrations against a non-production target. Validate record counts, data accuracy, and business rule compliance.

05
Production Migration

Execute the production migration with real-time monitoring, validation checkpoints, and rollback readiness. Verify before declaring success.

Every engagement starts with an assessment.

Not a proposal. Not a sales call. We tell you what we find, not what you want to hear. The Launchpad assessment maps your operation before any software work begins.
