SGWG Sep 26 Question re: FHIR

Hi -

Thank you for your participation today in the meeting! I'm repeating a question from the chat about the HL7 work that I wasn't able to answer. I'm hoping my terminology specialists here in the forum can provide an answer?

Question -
Live messaging of v2, v3, v3.x, FHIR and next FHIR in play all at once is an issue. Other than upgrading entire messaging - does HL7 or other have advise on something like this?

Thanks,
Karen
