I am attempting to upgrade our kola version (Victoria to wallaby). The docs suggest it should entail getting the new version of the kolla-ansible pkg & deps, updating the config files & then running “kolla-ansible upgrade”. However, what do we do if version N & version N+1 of kolla-ansible don't support the same host OS version?
We are currently planning upgrades from Ussuri through to Wallaby or later, and we have found that Victoria is the crossover version from Ubuntu 18.04 to 20.04 and supports both. So, we will upgrade to Victoria, then upgrade or rebuild our nodes to 20.04, then continue upgrading. We haven't yet looked to 22.04, but I expect that will be required in a later version and there will be a crossover which supports 20.04 and 22.04 for a similar approach.
All done first in dev and test clusters, of course.
HTH, Greg.
