Why each option
Clustered Data ONTAP 8.2 supports batch and rolling as the two non-disruptive upgrade methods for clusters of 8 or more nodes.
Batch upgrade divides the cluster into groups and upgrades multiple HA pairs simultaneously, making it efficient and supported for clusters of 8 or more nodes where rolling alone would be too time-consuming.
Parallel is not a defined non-disruptive upgrade methodology in clustered Data ONTAP 8.2.
Rolling upgrade sequentially upgrades one HA pair at a time across all nodes while keeping the cluster fully operational, and it is supported at any cluster size including 8 or more nodes.
Synchronous refers to a SnapMirror replication mode, not an upgrade technique in clustered Data ONTAP.
