Can multiple versions of HL7 FHIR be supported in parallel? How is backward compatibility and transition between FHIR versions supported?

Smile CDR is designed to enable multiple versions of the FHIR specification to be supported in a single installation of the software. At present, this is achieved through separate version-specific databases. We have also implemented experimental support for parallel support of multiple versions of FHIR in a single database, as well as automated translation between FHIR versions. This support could be expanded with guidance from specific customer requirements.
