If you convert your Snapmirror relationships from DP to XDP, as Tim mentioned, you can maintain your relationships between the 8.3 and 9.5 system. However, I would recommend upgrading as soon as you can get the chance. I believe 8.3.x is at the end of the support cycle. Remember to validate your environment against the IMT as you step through your upgrades.

I'd found the chart. Looks like my route is that I do need to upgrade my 8.3 cluster - possibly twice, if I want to do a more graceful update. (e.g. take DR To 9.1, let it 'bed in' for a week, take prod to 9.1, push DR up to 9.4, etc.).
I might look to XCP/rsync as possibilities too, as that's "just" a different kind of pain right now :).

The second chart on this page is what Tim was referring to:

Look at converting your SnapMirrors to XDP.
That became default for mirror in maybe 9.1 or 9.2. It allows for mirror between versions of ONTAP. I believe there is a chart showing compatibility someplace. Traveling now so not looking for links. Sounds be easy to find though

I've got a new cluster in, running the latest and greatest ONTAP version.
For reasons, the predecessor cluster is running a 'stable' platform, and hasn't been tracking the most recent updates.
It's a snapmirrored cluster.
I'm trying to figure out migration routes now.
Is there any equivalent of 7-mode -> CDOT TDP replication, or am I going to have to bite the bullet and do an update on the source cluster to a newer version?
And if so, because the snapmirror relationship that already exists, does that mean a 'stepped' approach of 8.3->9.1->9.4 (to 9.5 potentially) because that's what I'll need to do to preserve the snapmirror relationship with the replication partner?
I'm not overly keen on pushing up a major version number on both our prod/DR environment but if the choice is that or 'rsync/xcp' then I'll probably go with that.
I am just hoping there's a migration-assist option that means I don't have to do that, analogous to TDP from 7 mode.
