When upgrading a 2-node MetroCluster to a new ONTAP version, Switchover fails with the following error message:
Error: command failed: Unable to perform the MetroCluster operation because of a Data ONTAP version mismatch. All nodes in a MetroCluster configuration must have the same
version for both the current and default images. Upgrade or revert nodes as needed, then try the command again.
