+1. Log in to Gateway with a user that has the `Admin` role.
+1. Click on the `Admin` charm, then `Packages`.
+1. In the `Package Definitions` grid, select `Is Published` filter option on the `Is Published` column to show all published packages.
+1. For each published package version:
+    * Select the package.
+    * Click  `Unpublish` at the bottom of the `Definition` tab and click `Unpublish` on the confirmation pop-up dialog. A success message should appear. If it doesn't it means that there is a problem with the configuration in the `web.config` file for {{% ctx %}} Gateway, or the Application Services aren't healthy
+    * Click `Create New Version` then click `Save` and wait for the new version to be created.
+    * Click `Publish`. A success message should appear. If it doesn't it means that there is a problem with the configuration in the `web.config` file for {{% ctx %}} Gateway, or the Application Services aren't healthy.

+## Delete Old Execution Services
+   {{< alert type="note" title="Note" >}} This only needs to happen for upgrading to this release version as breaking changes were introduced as part of the cleanup of the NServiceBus endpoint and RabbitMQ queues.{{< /alert >}}
+
+1. Open a web browser.
+1. Navigate to `https://server.domain.com:9080/Explorer`, where `server.domain.com` is the fully qualified domain name of one of the application servers. Replace `9080` with new `httpGatewayEndpointPort` value if it was changed during configuration of the original installation.
+1. Expand `Cluster` then `Applications` then `Cortex.Innovation.Execution`.
+1. For all old execution applications:
+    * Click on the drop down menu and select `Delete Application`. Confirm application deletion by following the on-screen instructions.
+    * Give this a few minutes. If the application does not delete:
+        * Expand `Nodes`
+            * For each node:
+                * Expand the node and select the application that matches the engine version number of the application that is being attempted to be deleted.
+                * Expand each level up to and including `Code Packages`.
+                * Click on the drop down menu for `Code` and select `Restart`. Confirm application restart by following the on-screen instructions.
+            * Give this a few minutes. Once all nodes have been restarted the application should be deleted and disappear from the list of applications.
+
+Repeat the above instructions for the  `Flow Debugger`. In step 2 `server.domain.com` is the fully qualified domain name of the web application server.
