What is recomended for non-disruptive SVM-DR between source and destination during ONTAP upgrade?
- Last Updated:
- ONTAP 9.x
- SnapMirror relationships should be quiesced prior to upgrading
- 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
- It is generally recommended to upgrade the destination first, as you cannot replicate higher (ONTAP version) source to lower destination
