A method and system are provided for transparently migrating a storage object (aggregate) between nodes by one of the nodes (source), automatically verifying another node (destination) is configured to service the aggregate, and changing ownership of the aggregate based on the verifying to enable servicing of the aggregate at the destination. A cluster manager receives an aggregate migration request and provides the request to the source owning the aggregate. The source verifies the destination is configured according to a predetermined configuration for servicing the aggregate. Based on the verifying, the source offlines the aggregate and updates ownership information of the aggregate, thereafter allowing the destination to online the aggregate. The cluster manager provides the updated ownership information to all nodes in the cluster, so an access request intended for the aggregate may be received by any node and forwarded to the destination using the updated ownership information.
