The testing done is usually an upgrade from recent to next in
the pre-release beta testing, and us likely to remain that
way, because there is a cross-product explosion as
successive point releases issue, and frankly, the upstream
model is that the 'latest' is the mose secure (and hopefully
exhibiting a durable ABI/API profile, with some noted
exceptions mentioned in Release Notes)
I would _suspect_ that there would no issues to bumping from
an earlier 'point sub-version' directly to a later initially
released 'base' of a later 'point' sub-version with CentOS as
we do not back roll 'updates' into the 'base' image. Some
other rebuilds do.
As you are 'qualifying' a new sub-version level, this implies
that you have a set of behaviours you are testing for on a
deployment testing bench. I think the best advice one can
offer is:
try it and report here
and we'll all learn together ;)
