Data migration

ETL Pro

Move decades of data off old systems without losing a record.

Our toolkit and practice for data migration and integration. We extract from legacy databases, map and clean the data, load it into the new system and reconcile both sides, with checks agreed in advance.

What it does

Built around the real work

Legacy extraction

Pull data from old databases nobody wants to touch, including Oracle 8i.

Mapping you sign off

Field-by-field rules agreed with your team before anything moves.

Validation

Bad, duplicate and orphaned records are found and fixed before load.

Repeatable loads

Run the pipeline again and again until the trial migration is clean.

Reconciliation

Counts and totals checked on both sides, with a report you can file.

Secure handling

Sensitive records stay under access control throughout.
