Upgrading from v0.8 to v0.9
===========================
There are no special notes or considerations when upgrading from v0.8 to v0.9.
Due to a change in the API group that cert-manager deployments use
(`apps/v1beta1` to `apps/v1`), cert-manager deployments must first be deleted
before applying the new version. This will cause downtime until the new version
has been applied. To perform this action run:
.. code-block:: shell
kubectl delete deployments --namespace cert-manager \
cert-manager \
cert-manager-cainjector \
cert-manager-webhook
After this operation, follow the standard upgrade process as defined in the
:doc:`upgrade guide <./index>`.
