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.
