For adding a 9.7 node to a 9.8 NetApp cluster, which nondisruptive approach could be used?

For adding a 9.7 node to a 9.8 NetApp cluster, which nondisruptive approach could be used?

• A. Upgrade the node to 9.8 first
• B. Use the -allow-mixed-version- parameter
• C. Both upgrading to 9.8 and using -allow-mixed-version- parameter
• D. None of the above

Answer: (C)

When adding a node with a different ONTAP version into a cluster, NetApp allows a nondisruptive path by either upgrading the node before it joins or enabling mixed-version operation during the join. Upgrading the 9.7 node to 9.8 before adding it ensures the cluster runs a single version, while using the -allow-mixed-version- parameter lets you join a 9.8 cluster with a 9.7 node and operate in mixed-version mode temporarily. Both approaches are supported, so you can choose either method to achieve nondisruptive integration. If you opt for mixed-version, plan to complete the upgrade afterward, since the mixed state is temporary and some features may have limitations during that period.
