Legacy Healthcare Systems & Migration

Most NHS estates run on systems older than the standards now expected of them, and replacing them wholesale is rarely on the table. These articles cover the practical middle ground: what a legacy interface engine can and cannot do, how to integrate with an old system without rebuilding it, and how to phase a migration that does not stall halfway.

Common questions

Can you integrate with a legacy system without replacing it?
Usually yes. Most legacy clinical systems expose HL7 v2 over MLLP or a scheduled file feed, both of which are perfectly workable inputs. The integration layer absorbs the age of the system, which is what makes a phased migration possible at all.
When is a legacy interface engine no longer enough?
When the work has moved past message routing into terminology validation, profile conformance and multi-step orchestration, and every change still requires a specialist and a release. That is the point where the engine has become the bottleneck rather than the tool.
