7-Mode Transition Tool enables you to collect information about and assess 7-Mode controllers, hosts, switches and applications for transition. You can then migrate your data and configurations from 7-Mode to clustered Data ONTAP® by using either copy-based transition or copy-free transition.
While installing the tool, you must select either copy-based transition or copy-free transition as the migration method.
- Copy-based transition: Enables you to copy 7-Mode volumes and configurations to clustered Data ONTAP by using SnapMirror® technology.
- Copy-free transition: Enables you to connect 7-Mode disk shelves to target cluster nodes and transition configurations from 7-Mode systems to clustered Data ONTAP.
SnapMirror must be licensed on the 7-Mode storage system. If the 7-Mode system does not have a SnapMirror license, you can obtain a temporary SnapMirror license for transition from your sales representative.
