Public cloud services can be upgraded in one of two ways: an environment swap or an in- place
upgrade. An environment swap places the staging environment into the production environment. As
the swap occurs, the existing production environment is moved into the staging environment. An inplace upgrade replaces the existing binaries and settings with new binaries and settings.
