ONTAP 7-Mode Transition

Prerequisites for transitioning NFS configurations


NFS configurations are transitioned by the 7-Mode Transition Tool only when certain prerequisites are met on the 7-Mode system and the cluster. If any of the conditions are not met, the tool does not transition the configuration.

7-Mode prerequisites

  • NFS must be licensed.

  • If MultiStore is licensed, NFS must be enabled on the vFiler unit that owns the transitioning volumes.

  • For transitioning a Microsoft Active Directory (AD) based Kerberos server to a new SVM, a DNS entry must exist for the AD domain.

    Note To transition the Kerberos configuration, at least one LIF must be transitioned as part of the project and the LIF must be resolvable to a host name.
  • If you want to transition in-memory export rules, you must add them to the /etc/exports file before transition.

    The 7-Mode Transition Tool transitions only the persistent export rules that are defined in the /etc/exports file.

Cluster prerequisites

  • NFS must be licensed.

  • For transitioning a Microsoft AD-based Kerberos server to an existing SVM with DNS configured, a DNS entry must exist for the AD domain.

  • The clock skew between the Kerberos key distribution center (KDC) and the ONTAP system must be less than or equal to 5 minutes.
