Thankfully, I discovered today that OnTAP 9.6 will not support the 7 Mode Transition Tool, according to the Release Notes. I say "thankfully" because I'm about to deploy our first OnTAP Select cluster in the next few days and was planning to put 9.6 on it, however I need to run the 7MTT to transition content from an old 2220 so I will now deploy 9.5P6. To any NetApp engineers who read this, I would like to request that the 7MTT be made compatible with 9.6. 7-mode is supported through spring of next year, and this is the time where we will be pushing to get our last handful of small offices with old 7-mode based 2220s onto a cdot based system. I'm sure we are not alone. Would love to hear anyone else's thoughts on this!
Here's another update. After my discussions with the Partner Solution Center, I was informed that the next version of 7MTT (3.3.2) will support the transitions to 9.6P7 & 9.7P2. The tentative release date is 4/17/2020.
That may or may not happen. Support was officially removed for TDP (Trtansition Data Protection) Mirrors which is what is ultimately used between 7-mode and ONTAP. I've "heard" that if you open a case with support, there may be a work around. If there is, it likely will not (at least should not) be posted in any community forum.
Interesting. Thanks @TMACMD . I still think it should fully be supported through next Winter. This is the time when the final 7 mode transtions will likely be going on, as it will be for us.
Does anyone know/remember the flag in 7MTT that will allow it to work with 9.6 (now that TDP mirrors are back)? It was a setting file that had to be changed. I remember having to do this before when 9.5 first came out and 7MTT didn't originally work with it.
Wow @Andre_Clark I did not know that option existed! Very good to know. Let us know if you are able to test/verify that it truly works after doing that in 9.6!
So update on this. This option, which worked before, is not working now. I've reached out to support to see if there's an update or if there's a different file that I'm missing. I'll update once I have an answer.

I tested that config tweak option 9.7P2, and in my earlier response to similar topic in another thread. It does not allow 7MTT, however manual TDP works fine as stated in that BUG.
