Keep on mind that you're still going to need a storage system like Ceph
separate from Openstack whereas you may be used concept being native in

Besides that, migration is pretty straightforward. I assume you're already
running on KVM, so you should be able to snapshot and import your current
instances, volumes, etc.

Openstack and k8s are great together. Check out the Openstack Magnum
project, cloudprovider-openstack, and if you're trying to so multiattach
persistent volumes, Manila.

Does anyone have any experience migrating between the two, or any other

Follow one of the install guides on docs.openstack.org to do a manual
install so you get familiar with all the bits and bobs under the hood.
After that, pick a deployment project to create your production cluster.
Kolla-ansible, Openstack-ansible, Triple-O, and Juju are some popular ones.
