.. note::
It is strongly recommended that you validate the state of your undercloud
before starting any upgrade operations. The tripleo-validations_ repo has
some 'pre-upgrade' validations that you can execute by following the
instructions at validations_ to execute the "pre-upgrade" group::
openstack workflow execution create tripleo.validations.v1.run_groups '{"group_names": ["pre-upgrade"]}'

the example above but instead using the "pre-upgrade" group::

You can monitor the progress of the execution by getting its status and also
output::
mistral execution-get $ID
mistral execution-get-output $ID
When any of the validations fail the execution will have a ERROR status.
You can query the individual validations in the group to determine the exact
reasons that the validation fails. For example::
for i in $(mistral execution-list | grep tripleo.validations.*ERROR | awk '{print $2}'); do mistral execution-get-output $i; done
