Migrating ONTAP 8.3 to 9.5
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.

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

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

Re: Migrating ONTAP 8.3 to 9.5 [ In reply to ]
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 :).

Edward

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.
