# HL7 FHIR Converter

Beginning in HAPI FHIR 2.3, a new module called `hapi-fhir-converter` has been added to the project. This is an experimental feature so use it with caution!

This feature allows automated conversion from earlier versions of the FHIR structures to a later version.

The following page shows some basic examples. Please get in touch if you are able to contribute better examples!

## Importing the Module

To use the `hapi-fhir-converter` module, import the following dependency into your project pom.xml (or equivalent)

```xml

	ca.uhn.hapi.fhir
	hapi-fhir-converter
	${project.version}

```
