The VB app, the on-prem SQL, the Access database the accounts head still loves: Lunai modernises legacy applications by strangling them safely. Users keep working; the new surface grows around the old core.
Strategies we use
Rewrite is the last option. APIs, new UIs, and cloud databases in front of a stable core usually ship value first.
- Inventory of jobs, interfaces, licences and tribal knowledge
- Strangler-fig: new modules beside the old executable
- Data migration rehearsed until cutover is boring
- Terminal users get a web or mobile front they will accept
Risk you can brief to the board
We time-box spikes, keep a rollback, and never schedule go-live on a filing deadline.
- Parity tests against the legacy reports
- Performance budgets on the new stack
- A decommission checklist with licence savings dated
If your India operation still depends on a machine only one person understands, Lunai will modernise that legacy application in stages.
