The version of ontap for our newly purchased FAS2750 was ver 9.9.1. We have existing cluster environment (ontap 9.7P18) and would like to downgrade from ontap ver 9.9.1 to 9.7 in order to join that environment.
I have checked and it seems that I need to Revert to ver9.8 once.
The downgrade procedure is described in the published documents only for environments with a cluster configuration, but not for downgrading (upgrading) the node before cluster configuration on new equipment.
Is it necessary to do a cluster setup once?
I would appreciate it if you could tell me the procedure to downgrade the node before cluser setup.
