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.
