  • ONTAP 9.x
  • SVM-DR

Answer

  1. SnapMirror relationships should be quiesced prior to upgrading
  2. Plan to upgrade to supported ONTAP versions between the source and destination as advised by SnapMirror DR Interoperability
    • NOTE: If the destination is running a later/newer version the relationship cannot be reversed
  3. It is generally recommended to upgrade the destination first, as you cannot replicate higher (ONTAP version) source to lower destination
