Reviewing cluster upgrade requirements

Before updating the ONTAP software, you must verify that your cluster meets the general requirements. Some configurations and features also have requirements that you should understand.

  • Cluster update requirements
    There are release and configuration requirements that your cluster should meet before you perform an update. Additionally, there are mixed version requirements that you should be aware of while you are performing the update.
  • Guidelines for estimating the duration of the upgrade process
    You should plan for at least 30 minutes to complete preparatory steps, at least 30 minutes to upgrade the cluster (depending on the number of nodes), and at least 30 minutes to complete post-upgrade steps.
  • Understanding LIF migration in the upgrade process
    During the upgrade process, LIFs are migrated based on the upgrade method. Depending upon the upgrade method, the LIF failover policy might or might not be used.
