SVM DR while migrating data using 7mtt tool

mp090 — Wed, 04 Jun 2025 11:08:19 GMT

Hello,

I am doing copy based migration using 7mtt tool. I got a 7mtt project setup with couple of volumes mirrored to cluster mode filer. Now I want to setup DR from cluster mode filer to DR cluster mode filer. Is it possible to do so before 7mtt project cut over? So that data is mirrored from 7 mode to cluster mode using 7mtt tool and then from cluster mode to DR cluster mode using SVM DR?

I would assume that you would be able to do that. This would be a cascade style relationship and the second hop can only be done through the CLI. Only one hop if you will is supported by NetApp.

When I migrated the migration tool was not as mature and I complete all migrations manually, its actually much more simple that it seems.

In the manual process I needed to migrate volumes which were snapmirrored from a 7mode appliance to a 7mode appliance in another data center. The volume was large and creating a new snapmirror would have left it without protection for several days.

I snapmirrored the source volume to the new ontap9 appliance and snapmirrored the destinations volume to the new ontap9 appliance in the second data center. During after cut over I created the snapmirror relationship between the new ontap9 volumes the snapmirror was converted to new ontap9 snapmirror and resyncronnised without massive data transfer.

I believe this is similar to what you are trying to do, I think the tool can also do this.
