Modernising Legacy Software Without Halting Operations

9 min readiDeo technical team

An old system can seem limited, yet simultaneously underpin processes that no one has documented. Replacing it all at once concentrates risks; maintaining it indefinitely also carries a cost.

Map Visible and Hidden Dependencies

Before writing any code, it's essential to understand who uses the system, what data it receives and delivers, what reports it generates, and what exceptions it resolves. Interviewing those who work with it often uncovers functions not detailed in manuals.

Migrate by Capability

Separating modules, creating temporary integrations, or moving user groups allows for the validation of the new environment in stages. The plan should include testing, data reconciliation, and a reasonable rollback path for each change.

Adoption is Part of the Project

New screens don't fix a poorly understood process. Prototypes, user testing, and documentation help to refine the solution before wider deployment, without promising a transition free of any disruption.
