This script will perform a ${SOURCE_SERIES^} to ${TARGET_SERIES^} upgrade.
Once you start the upgrade there is no going back.
Note that the upgrade targets impacting the data
plane as little as possible, but assumes that the
control plane can experience some down time.
This script executes a one-size-fits-all upgrade,
and given that the tests implemented for it are
not monitored as well as those for a greenfield
environment, the results may vary with each release.
Please use it against a test environment with your
configurations to validate whether it suits your
needs and does a suitable upgrade.
Are you ready to perform this upgrade now?
