Delphi estate: new interfaces without a big-bang rewrite
Extending an existing Delphi suite with REST and batch interfaces to a new CRM—the legacy app stays operational; deeper migration can follow later.
Delphi estate: new interfaces without a big-bang rewrite
Delphi development
The Challenge
Legacy data must sync with CRM
A proprietary data format needed exchange with a SaaS CRM without a risky freeze; a rewrite was not affordable short term.
Our Solution
Adapter layer and controlled releases
We encapsulated import/export in a service module with retries and audit logs; REST endpoints were versioned. Tests validated round trips against reference datasets.
Results
Operations without downtime
The legacy stack stays productive; CRM-led projects receive data on time. Follow-on releases supported from East Frisia.
