Before you start transition, you should verify that you have met all of the prerequisites for transition.

ONTAP version requirements

Item Yes

Supported 7-Mode version NetApp Interoperability Matrix Tool

Your cluster must be running one of the following Data ONTAP versions:

  • Data ONTAP 8.2.x

  • Data ONTAP 8.3.x

You must transition to one of the following ONTAP releases:

  • Using 7-Mode Transition Tool 3.3.3:

    • ONTAP 9.8 or earlier supported releases

  • Using 7-Mode Transition Tool 3.3.2:

    • ONTAP 9.7P2 or later 9.7 P release (earlier 9.7 releases are not supported)

    • ONTAP 9.6P7 or later 9.6 P release (earlier 9.6 releases are not supported)

    • ONTAP 9.5 or earlier ONTAP 9 release

    • Clustered Data ONTAP 8.1.4P4 or later 8.x release

  • Using 7-Mode Transition Tool 3.3.1:

    • ONTAP 9.5 or earlier ONTAP 9 release

    • Clustered Data ONTAP 8.1.4P4 or later 8.x release

Licensing requirements

Item Yes

SnapMirror license is enabled on the 7-Mode system

SnapMirror licenses are enabled on the primary and secondary clusters for transitioning a volume SnapMirror relationship

CIFS license is enabled on the cluster, if it is enabled on the 7-Mode system

NFS license is enabled on the cluster, if it is enabled on the 7-Mode system

iSCSI license is enabled on the cluster, if it is enabled on the 7-Mode system

FC license is enabled on the cluster, if it is enabled on the 7-Mode system

Other feature licenses, if available on the 7-Mode system, are added to the cluster

SnapMirror requirements on the 7-Mode system

Item Yes

SnapMirror license

options snapmirror.enable on

options interface.snapmirror.blocked ""

Verify if one of the following is true:

  • The snapmirror.access option is set to all

  • The snapmirror.access option is set to the IP addresses of all the intercluster LIFs on the cluster

  • If the snapmirror.access option is set to legacy and the snapmirror.checkip.enable option is off, the SVM name is added to the /etc/snapmirror.allow file

  • If the snapmirror.access option is set to legacy and the snapmirror.checkip.enable option is on, the IP addresses of the intercluster LIFs are added to the /etc/snapmirror.allow file

Volume settings on the 7-Mode system

Item Yes

Volume is online

Volume is not restricted

The following volume options are disabled:

  • no_i2p

  • read_realloc

  • nvfail

Managing access to the cluster

Item Yes

SSL is enabled

HTTPS is allowed on the cluster-management LIF

system services firewall policy show

Managing access to the 7-Mode system

Item Yes

HTTPS is enabled

options httpd.admin.ssl.enable on

SSL is enabled

secureadmin setup ssl

options ssl.enable on

SSLv2 and SSLv3 are disabled

options ssl.v2.enable off

options ssl.v3.enable off

Networking requirements

Item Yes

Cluster is reachable using the cluster-management LIF

One or more intercluster LIFs are set up on each node of the cluster For multipathing, two intercluster LIFs are required on each node

Static routes are created for the intercluster LIFs

7-Mode system and cluster are reachable from the Windows system on which 7-Mode Transition Tool is installed
