Stage 6. Complete the upgrade
During stage 6, ensure that the new nodes are set up correctly. If one of the new nodes has a unified target adapter, you must restore any port configurations and might need to change the personality of the adapter. You should also set up Storage Encryption if the new nodes are encryption-enabled. You should also decommission the old nodes.
For MetroCluster FC configuration, you must replace the disaster recovery/failover site nodes as soon as possible. Mismatch in controller models within a MetroCluster is not supported because controller model mismatch can cause disaster recovery mirroring to go offline. Use the command -
skip-metrocluster-check true option to bypass MetroCluster checks when you are replacing nodes at second site.
