Earlier this year, we here at Mirantis found ourselves in a situation where we needed to upgrade across two OpenStack releases.
The need for an OpenStack cloud upgrade strategy has been around since OpenStack’s second release, Bexar, meant there was something to upgrade to. For many companies and teams, the complexity of upgrading has meant it was easier to simply migrate workloads from the old cloud to a new cloud rather than directly upgrading at all. Even today this is an option, of course, but creating a whole new cloud alongside the old one means essentially doubling your hardware and management investment.
