Modernise legacy spreadsheets and ageing tools

Replace fragile Access databases, macro-heavy Excel, and ageing on-prem tools with maintainable web apps and integrations. We migrate data carefully and phase cutover so the business keeps running.

Overview

Legacy modernisation replaces Access databases, macro Excel, and abandoned software with web apps and integrations. Fear of losing history stops many projects; we migrate with validation, parallel run, and rollback plans.

Sometimes wrap-and-integrate beats full replacement. Discovery tells you which.

Legacy System Modernisation FAQs

Answers to questions Australian businesses ask before starting this work.

Will we lose historical data?+

Not if scoped correctly. We archive legacy data, migrate active records, and reconcile counts before cutover.

How long can parallel run last?+

Typically 2–6 weeks depending on cycle. Finance and ops sign off when numbers match.
