ONTAP 7-Mode Transition

Preparing for MetroCluster configuration transition

Contributors netapp-barbe

Before transitioning to a MetroCluster configuration, you must understand the requirements and considerations for transitioning 7-Mode volumes to a MetroCluster configuration in ONTAP.


  • The MetroCluster configuration in ONTAP must already be set up.

  • The SVM type must be sync-source.

  • The 7-Mode controllers must not be in a taken over state or waiting for a giveback.

  • The nodes in the MetroCluster configuration in ONTAP must not be switched over or waiting for a switchback.


  • Transitioning SnapLock Compliance volumes is not supported if the target cluster is in a MetroCluster configuration.

  • You can transition volumes from a 7-Mode controller, HA configuration, or MetroCluster configuration to a MetroCluster configuration in ONTAP as stand-alone volumes.

  • If a 7-Mode MetroCluster configuration has volumes that are in volume SnapMirror relationships with volumes in another 7-Mode controller, you can transition the SnapMirror relationships as primary and secondary relationships.

    You should install the 7-Mode Transition Tool on each MetroCluster site and transition the volumes from each site.

  • Different subnets configured for a 7-Mode fabric MetroCluster configuration cannot be configured on the MetroCluster configuration in ONTAP.

  • The preferred port configured in a 7-Mode fabric MetroCluster configuration cannot be configured for the MetroCluster configurations in ONTAP.

  • If your 7-Mode fabric MetroCluster configuration is using Brocade 6510 switches, you can share the existing switch fabrics with the new MetroCluster configuration in ONTAP.

    It is best to share the switch fabrics only for the duration of the transition.

  • The cron job schedules created during transition are not replicated to the remote site, and therefore the negotiated switchover fails after transition.

    You must manually create the cron job schedules on the remote site after the transition.
