@P, Pioline (Cognizant) Welcome to Microsoft Q&A Forum, Thank you for posting your query here!
I see that your question is related to migrating huge amount of data from Azure FHIR Server to Azure Health Data Services.
Could you please confirm if you have explored the option to Export the data from Azure FHIR Server to Azure Datalake Storage? By using the bulk $export
operation in the FHIR service, you can export data. Before you attempt to use $export
, make sure that your FHIR service is configured to connect with an Azure Data Lake Storage Gen2 account. Once the data is in Azure Datalake Storage, you can use the $import operation in Azure Health Data Services to import the data into the FHIR service.
