Tried performing Takeover by allowing version mismatch but it failed below error:

Warning: Initiating a takeover while the partner is running a mismatched ONTAP

version is not recommended, unless you are performing a nondisruptive

upgrade or downgrade. Do you want to continue? {y|n}: y

Error: command failed: Failed to initiate takeover. Reason: partner versions of

WAFL and/or RAID are newer than this node.
