I doubt on creating a relationship with source running Clustered Data ONTAP and 7 mode as the vault, because, SnapVault in 7-Mode is qtree based, whereas SnapVault in clustered Data ONTAP is volume based and is able to retain storage efficiency savings during transfers. From the perspective of the primary volume, there's no change. From the perspective of the secondary—vault—volume you end up creating a new clustered Data ONTAP vault that requires a baseline (because it is a net-new relationship). This raises the question of what to do with all the data stored in the 7-Mode vault.
Note that the three-month cutoff is a guideline, not a hard rul

Question: I have a huge migration project ahead of me, and I'd like to leave 4 controllers on 7 mode. In order to do that, I'd need to mirror them to a 5th 7-mode system. So my question is:
Can I SnapVault from a 7-Mode filer to a CDOT filer (8.2.1 --> 8.3 specifically)? I'd need to leave this in place indefinately, otherwise I'd need swing gear in foriegn countries to pull of CDOT migrations, which I def don't want! Link to Netapp document please, I can't find any. If I can't, what is my alternative?

I don't think you can snapvault to a cdot cluster.
You can create an TDP relationship (transitional snapshot), but snapvault works very different in cdot 8.3.x. It's based on snapmirror labels, but you can't snapmirror (TDP) a snapvault secondary to cdot.
That will fail.
