+Steps:
+- [ ] bump .ci-operator.yaml if needed (as a separate PR and wait until the changes gets propagated to https://github.com/openshift/release/tree/master/ci-operator/config/openshift/ of the corresponding CI definition)
+- [ ] bump go version in a go.mod file if needed (check go.mod of the corresponding kubernetes release under https://github.com/kubernetes/kubernetes/branches)
+- [ ] bump all k8s.io/*, github.com/openshift/* and other relevant dependencies (you can consults the corresponding go.mod file as mentioned previously)
+- [ ] (recommended) commit all the go.mod and go.sum changes separatelly from `go mod vendor` changes
+- [ ] run "go mod vendor" and commit the changes
+- [ ] build the code (e.g. by running make) and adjust the code if needed to make the building step compile successfully
+- [ ] run unit tests (e.g. by running make unit-tests) successfully
+- [ ] commit the code adjustments if there are any

 the maximum number of evictions per node to 2 aligning with KubeVirt defaults around concurrent live migrations.
 Those two values can be customized with `evictionLimits.total` and `evictionLimits.node` parameters.
