The point of 7mtt is to mirror to ONTAP and then cut-over. Yes, it is one way but we have customers doing it quite frequently.
It is not a move, it is a SnapMirror (Transition Data Protection or TDP Mirror).
As along as the mirror portions finish, cutting over is pretty straight forward.

If something unforeseen happens and a manual cut-over has to happen, so be it. It should not be too difficult.

Source is already 7mtt’d but shipping a 7 mode system and need a copy we can run from. 

Concerned that if the 7mode system does not make the move well we would have to manually finish 7mtt.

Um... Use 7-mode transition tool from the support site

It allows one way TDP mirrors from 7-mode to any ONTAP release up to 9.5

It will not work with 9.6

No need to downgrade. Honestly to do that is a ton of work and not all platforms can go back that far anyway.

Your NetApp sales team really should have informed you about 7MTT.

Hello,

We are the middle of move planning and need to snapmirror some 7 Mode data.

The gear we have for the destination is from the factory with 9.5.

The usual netboot is throwing errors.

Any suggestions?

Thanks,
Carolyn
