Since the Cloud and Server apps versions use different APIs, all connectors created in BigQuery Connector for Jira Server should be manually re-created in the Jira Cloud app. This means that the connectors/data sources that have been previously created in BigQuery Connector for Jira app cannot be migrated or copied automatically from Server to Cloud.
This requires closer attention to the details during the Data Sources recreation. Users are advised to check the Jira fields used in the data sources and map them with the relevant fields in Jira Cloud. You should keep in mind that not all fields from Jira Server are available in Jira Cloud and that fields names may differ.
Since the fields available for export are different, some of the report's concepts should be reconsidered during the migration planning.
