Re: Migrating ONTAP 8.3 to 9.5

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.

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 :).
