Hey everyone; I'm planning an upgrade from OSA 18.1.17 to OSA 19.0.9.
Now, the upgrade notes say:

The supported upgrade path from Xenial to Bionic is via re-installation of the host OS across all nodes and redeployment of the required services. The Rocky branch of OSA is intended as the transition point for such upgrades from Xenial to Bionic. [...]

Currently, I am running 16.04 Xenial on all my machines, but I'd also like to upgrade them to 18.04. This wording confuses me a bit - does this mean I should do the OS upgrade first, while on Rocky?
