A migration management service can partition a service and migrate resource data without requiring the resource to be taken offline. The migration management service can receive a request to partition a service into multiple partitioned services that are independent of one another. The request can identify one or more resources associated with each partition. For example, a single service receiving data for resources throughout the world can be divided into multiple regional services, where each regional service is independent of the others. The migration management service can track the status of data while migrating. As new messages are received from resources, the migration management service can determine the migration status of the resources. If the data for a resource is not migrated, the original data store can be used. However, if the data is migrated, the message can be forwarded to the appropriate partition for further processing.
