I think the two month phase is pretty accurate. Deployment itself is not that time intense and changing your applications to be container friendly is not either.

The time intensive phase during the first Kubernetes deployment is changing the mindset of the engineering team and everyone involved in IT.

Kubernetes IMHO is pretty much like moving from college into work life and adapting to the fact that requirements for a decent adult life are very much different from a college life.

That's as may be for Kubernetes, but the GP specifically stated "that's the case for everything, not only for kubernetes", which struck me as an extraordinarily broad claim.

One might reasonably expect "everything" to include traditional deployment methods that require no changing of mindsets (not that that's likely a factor in my nascent startup example).

Transition phases actually make sense even if you apply "everything" instead of just "Kubernetes" considering how every company transitions through stages in terms of tooling.

Think being a startup where deployments most likely will be manual and undocumented, upgrading to an initial automation using some scripting, transitioning to CI/CD, etc.

So from various experiences at companies of all sizes I would actually support such a broad claim, since companies are basically transitioning all the time through new phases to greener pastures. That of course assumes that the company values constant improvements and uses an iterative process for growth and change.
