+// Regular procedure for gitops workflows migration that requires (or the user optionally wants) a rebuild of the workflow image.
+// The caller document must set the following attributes: (see: upgrade_1_37_0_to_1_37_1.adoc as example)
+// current_operator_version, next_operator_version and next_swf_builder_image.
+:page-partial:
+
+*Pre-operator upgrade steps:*
+
+. If the workflow is configured to use persistence, you must back up the workflow database.
+Ensure that your database backup includes all database objects, not just the table's information.
+
++
+. Ensure that you have a copy of the corresponding `SonataFlow` CR, as well as any other Kubernetes resources created for that workflow.
+For example, if you are using custom property configurations, you will need a copy of the user-provided `ConfigMap` with the `application.properties` file.
+
++
+. Delete the workflow by using the following command:
+
++
+[source,terminal]
+----
+$ oc delete -f <my-workflow.yaml> -n <target_namespace>
+----
+
+*Post-operator upgrade steps:*
+
+[start=4]
+. Rebuild the workflow image using the new {product_name} `{next_operator_version}` workflow builder `{next_swf_builder_image}`, by considering the following:
+
++
+By default, the {operator_name} generates a workflow `Deployment` with the `imagePullPolicy: IfNotPresent`.
+Meaning that, if an already deployed workflow `my-wofklow`, is redeployed with the same image name, even when that image was rebuild, the old already downloaded image will be picked-up.
++
+To ensure the new image is picked-up you can:
+
+* Use a new tag, and configure the workflow with it.
++
+[source,yaml]
+----
+current image: quay.io/my-images/my-workflow:1.0
+new image: quay.io/my-images/my-workflow:1.0-1
+----
++
+[source,yaml]
+----

+      image: quay.io/my-images/my-workflow:1.0-1
+  flow:
+    # the workflow definition (don't change)
+----
++
+* Preserve the image name, and configure the workflow with the `imagePullPolicy: Always`.

++
+[IMPORTANT]
+====
+In any of the alternatives, when you rebuild the image (in your local environment), and when you redeploy the workflow (using the `SonataFlow` CR), you must not change
+the workflow definition, nor any workflow related assets. This includes the name, version, and description.
+====
+
+. Ensure that any Kubernetes resource for that workflow, such as the user-provided `ConfigMap` with `application.properties`, is created before you redeploy the workflow.
+
++
+. Redeploy the workflow by using the following command.
++
+[source,terminal]
+----
+$ oc apply -f <my-workflow.yaml> -n <target_namespace>

+This guide describes how to upgrade the {operator_name} `{current_operator_version}` installed in an OpenShift cluster to the version `{next_operator_version}`.
+
+.Prerequisites
+* An OpenShift cluster with admin privileges and `oc` installed.
+
+== Procedure
+
+To upgrade an {operator_name} `{current_operator_version}` installation to the version `{next_operator_version}`, you must execute this procedure:
+
+=== Overall upgrade procedure
+
+It is recommended to read and understand all the steps of the procedure before executing.
+Interested parties might automate the procedure according to their convenience or infrastructure, for example, keeping all the `SonataFlow` CRs in a GitHub repository, might help considerably to implement automation, etc.
+
+. Increase the Job Service retry interval before starting the upgrade by following these <<config_jobs_service_retry_interval, steps>>.
+. Execute the steps `1` and `2` of the upgrade for every workflow with the <<workflows_dev_profile, dev profile>>.
+. Execute the steps `1`, `2` and `3` of the upgrade for every workflow with the <<workflows_preview_profile, preview profile>>.
+. Execute the steps `1`, `2`, `3` and `4` of the upgrade for every workflow with the <<workflows_gitops_profile_image_rebuild, gitops profile>>.
+. Execute the step `1` of the <<data_index_upgrade, Data Index>> upgrade.
+. Execute the step `1` of the <<jobs_service_upgrade, Job Service>> upgrade.
+. Upgrade the {operator_name} to the version `{next_operator_version}` <<operator_upgrade_procedure, following this procedure>>, and verify that the new version is running.
+. Finalize the <<data_index_upgrade, Data Index>> upgrade by continuing from step `2`.
+. Finalize the <<jobs_service_upgrade, Job Service>> upgrade by continuing from step `2`.
+. Finalize the upgrade for the workflows with the <<workflows_gitops_profile_image_rebuild, gitops profile>> by continuing from step `5`.
+. Finalize the upgrade for the workflows with the <<workflows_preview_profile, preview profile>> by continuing from step `4`.
+. Finalize the upgrade for the workflows with the <<workflows_dev_profile, dev profile>> by continuing from step `3`.
+. Restore the Job Service retry interval by following these <<restore_jobs_service_retry_interval, steps>>.
