Pretty much, each release is needed to be upgraded too, before starting the next. Need to be on a SLURP (2023.1) to be able to skip a release, but still not multiple. SLURP lets you skip the non-SLURP between releases.

Details on SLURP https://releases.openstack.org/#slurp

Hi,

if I remember correctly, Bobcat is the first version that supports
skipping one release. So you'll have to go through both Ussuri and
Victoria. Someone please correct me if I'm wrong.
