Applies to

  • ONTAP 9
  • Non-Disruptive Upgrade (NDU)
  • MetroCluster cluster (MCC)

Answer

During the ONTAP's NDU period, keep at least one pair have the same ONTAP version between the Active site and the DR site.
For example, A1/A2 are nodes from A site and B1/B2 are nodes from B site. If A1-B1/A2-B2 are each DR paired, then an upgrade sequence of either A1 / B1 ->  A2 / B2 or A2 /B2->A1 / B1 is recommended.
