# You can specify the package names to update as options in the yum update command.
You do not need to restart any services after you update.

#. Update stack environment of the existing overcloud:
If you use heat templates from default location
(`/usr/share/openstack-tripleo-heat-templates`), it's possible that these
templates have changed when updating undercloud machine. You should update
the existing overcloud to reflect any changes in template and environment
files. The reason is that CLI commands which change existing overcloud pass
new template to Heat but reuse existing environment of the overcloud so a
new resource type referenced in updated template might be missing in the
existing environment::
openstack overcloud deploy --templates -e /usr/share/openstack-tripleo-heat-templates/overcloud-resource-registry-puppet.yaml -e <all extra files>
.. note::
Make sure you pass all environment files you used when deploying
overcloud.
