Workflow for HL7v2 to FHIR conversion

[1hamzaiqbal]

I am working on converting HL7v2.5.1 ORU messages to HL7 FHIR messaging using the CLI interface and Liquid engine. After converting I am attempting to enter the FHIR bundle into a HAPI FHIR server.

Is it possible to use this tool and simultaneously maintain consistency of IDs and resolve issues with default values (code system URLs)? Not sure if what I want to do is possible given the fact that the CLI and workflow I'm using doesn't check for already existing IDs before sending a bundle containing multiple resources to the server.

Any advise on this would be appreciated -- just looking for clarification regarding how to execute what I'm trying to do.
