 resolution and at the end will create a PR for you.
 
 Here are the steps:
-1. Create a new BugZilla with the respective OpenShift version to rebase (Target Release stays ---),
-   Prio&Severity to High with a proper description of the change logs.
-   See [BZ2021468](https://bugzilla.redhat.com/show_bug.cgi?id=2021468) as an example.
+1. Create a new Jira ticket under OCPBUGS with the respective OpenShift version to rebase,
+   Target Backport Version to the previous minor version + .z
 2. It's best to start off with a fresh fork of [openshift/kubernetes](https://github.com/openshift/kubernetes/). Stay on the master branch.
 3. This script requires `jq`, `git`, `podman` and `bash`, `gh` is optional.
 4. In the root dir of that fork run:
 ```
-openshift-hack/rebase.sh --k8s-tag=v1.25.2 --openshift-release=release-4.12 --bugzilla-id=2003027
+openshift-hack/rebase.sh --k8s-tag=v1.25.2 --openshift-release=release-4.12 --jira-id=OCPBUGS-90150
 ```
 
 where `k8s-tag` is the [kubernetes/kubernetes](https://github.com/kubernetes/kubernetes/) release tag, the `openshift-release`
-is the OpenShift release branch in [openshift/kubernetes](https://github.com/openshift/kubernetes/) and the `bugzilla-id` is the
-BugZilla ID created in step (1).
+is the OpenShift release branch in [openshift/kubernetes](https://github.com/openshift/kubernetes/) and the `jira-id` is the
+Jira ticket number created in step (1).
 
 5. In case of conflicts, it will ask you to step into another shell to resolve those. The script will continue by committing the resolution with `UPSTREAM: <drop>`.
 6. At the end, there will be a "rebase-$VERSION" branch pushed to your fork.
