 * `configuration` - (Optional) The configuration string for the workspace that you create. For more information about the format and configuration options available, see [Working in your Grafana workspace](https://docs.aws.amazon.com/grafana/latest/userguide/AMG-configure-workspace.html).
 * `data_sources` - (Optional) The data sources for the workspace. Valid values are `AMAZON_OPENSEARCH_SERVICE`, `ATHENA`, `CLOUDWATCH`, `PROMETHEUS`, `REDSHIFT`, `SITEWISE`, `TIMESTREAM`, `XRAY`
 * `description` - (Optional) The workspace description.
+* `grafana_version` - (Optional) Specifies the version of Grafana to support in the new workspace. Supported values are `8.4` and `9.4`. If not specified, defaults to `8.4`. Upgrading the workspace version isn't supported, however it's possible to copy content from the old version to the new one using AWS official [migration tool](https://github.com/aws-observability/amazon-managed-grafana-migrator).
 * `name` - (Optional) The Grafana workspace name.
 * `network_access_control` - (Optional) Configuration for network access to your workspace.See [Network Access Control](#network-access-control) below.
 * `notification_destinations` - (Optional) The notification destinations. If a data source is specified here, Amazon Managed Grafana will create IAM roles and permissions needed to use these destinations. Must be set to `SNS`.
