Abstract: Method and system for a non-disruptive migration of a source virtual storage system from a source cluster to a destination cluster is provided. The method includes monitoring a current transfer rate for migrating information from the source cluster to the destination cluster during a migration operation; iteratively reducing a rate at which I/O requests are processed until a transfer rate for transferring the information from the source cluster to the destination cluster within the duration is reached; and entering a cutover phase for the migration operation when the virtual storage system presented by the source cluster is taken offline for the duration and after the information is migrated to the destination cluster, the virtual storage system is presented by the destination cluster.
