Use these steps to complete the upgrade in ONTAP 9.7 or earlier.
Mapping network ports using ONTAP 9.7 or earlier
To enable node3 and node4 to communicate with each other in the cluster and with the network after the upgrade, you need to ensure the physical ports are correctly configured with the settings for the intended use, such as cluster, data, and so on.
Performing final upgrade steps in ONTAP 9.7 or earlier
To complete the procedure of upgrading by moving storage, you need to delete any unused ports and LIFs from the new nodes, re-enable storage failover or high availability, configure the Service Processor (SP), install new licenses, and set up AutoSupport. You might also need to set up Storage or Volume Encryption and configure the FC or CNA ports.
