# Upgrading from IBM Business Automation Application Engine (App Engine) 19.0.3 to 20.0.1
2
+
3
+
These instructions cover the upgrade of IBM Business Automation Application Engine (App Engine) from 19.0.3 to 20.0.1.
4
+
5
+
## Introduction
6
+
7
+
If you installed App Engine 19.0.3 and want to continue to use your 19.0.3 applications in App Engine 20.0.1, you can upgrade your applications from App Engine 19.0.3 to 20.0.1.
8
+
9
+
## Step 1: Update the custom resource YAML file for your App Engine 20.0.1 deployment
10
+
11
+
Get the custom resource YAML file that you used to deploy App Engine for 19.0.3, and edit it by following these steps:
12
+
13
+
1. Change the release version from 19.0.3 to 20.0.1.
14
+
15
+
2. Add `appVersion: 20.0.1` to the `spec` section. See the [sample_min_value.yaml](configuration/sample_min_value.yaml) file.
16
+
17
+
3. Update the `application_engine_configuration` and `resource_registry_configuration` sections.
18
+
* Automatic backup for Resource Registry is recommended. See [Enabling Resource Registry disaster recovery](https://www.ibm.com/support/knowledgecenter/SSYHZ8_20.0.x/com.ibm.dba.managing/topics/tsk_enabling_disaster_recovery.html) for configuration information.
19
+
20
+
* If you just want to update App Engine with the minimal required values, use the values in the [sample_min_value.yaml](configuration/sample_min_value.yaml) file.
21
+
* Add `admin_user` to the `application_engine_configuration` sections.
22
+
* Change the image tags from 19.0.3 to 20.0.1 in all sections.
23
+
24
+
* If you want to use the full configuration list and customize the values, update the required values in the `application_engine_configuration` and `resource_registry_configuration` sections in your custom resource YAML file based on your configuration. See the [configuration list](https://www.ibm.com/support/knowledgecenter/SSYHZ8_20.0.x/com.ibm.dba.ref/k8s_topics/ref_ae_params.html) for each parameter.
25
+
26
+
## Step 2: Update the configuration sections for other deployments
27
+
28
+
To update the configuration sections for other components, such as User Management Service and IBM Business Automation Navigator, go back to the relevant upgrade page to follow their upgrade documents to update your custom resource YAML file.
