# Upgrade

## Overview

The following procedures apply to the WorkflowGen 9.3.0 (v9.3 Beta) upgrade pack, available at <https://github.com/advantys/workflowgen-releases/releases>.

## Package contents

The upgrade pack is distributed as a compressed file containing the following folders:

* `Inetpub`: WorkflowGen web application files
* `Program Files`: WorkflowGen Windows Services files
* `Databases`: WorkflowGen database update and creation files

## IIS server

Stop the IIS server (or at least your WorkflowGen web applications) if other websites are using the same IIS server.

## WorkflowGen Windows Services

Stop the WorkflowGen Directory Sync and Engine services in the Windows Services Management Console.

## Backup

### Application and data files

Back up the following folders:

* `DRIVE:\Inetpub\wwwroot\wfgen`
* `DRIVE:\Program Files\Advantys\WorkflowGen`

If the file storage path isn't the standard `DRIVE:\Inetpub\wwwroot\wfgen\App_Data` path, then you have to back up the corresponding folder.

### Database

Perform a standard database backup using your DBMS tools.

## Update WorkflowGen web application files

### Delete deprecated Node.js application files and folders

Verify if the following deprecated files and folders used by Node.js-based applications still exist in your `\wfgen` folder, and delete them if they do.

1. Delete the following files and folders from the `\wfgen\graphql` folder:
   * `\controllers`
   * `\models`
   * `\node_modules`
   * `\services`
   * `\utils`
   * `config.js`
   * `config.production.js`
   * `server.js` <br>
2. Delete the following files and folders from the `\wfgen\hooks` folder:
   * `\controllers`

   * `\services`
   * `\utils`
   * `config.js`
   * `config.production.js`
   * `server.js`

### Delete deprecated assembly files

Delete the following deprecated assembly `.dll` files from the `\wfgen\bin`, `\wfgen\ws\bin`, and `\Program Files\Advantys\WorkflowGen\services\bin` folders:

* `Advantys.Directories`
* `Advantys.Directories.Web.UI.Administration`
* `Advantys.Web.UI.Charting`

### Copy the upgrade pack content

Copy and overwrite the upgrade content from `Update\Inetpub\wwwroot\wfgen` to your WorkflowGen web application folder. By default, the suggested physical path is `DRIVE:\Inetpub\wwwroot\wfgen`.

{% hint style="warning" %}

* Domain users and the Windows accounts used to run the WorkflowGen IIS application pool and Engine service must have read and write permissions for the `\wfgen\App_Data` folder.
* Do **NOT** copy and overwrite your existing `DRIVE:\Inetpub\wwwroot\wfgen\web.config` file if you want to keep your current WorkflowGen configuration settings and database connection information.
* It’s possible that the following default CSS files have been updated in this release and could overwrite any changes you had made in your existing installation:
  * `\wfgen\App_Themes\Default\portal\css\Default.css`
  * `\wfgen\App_Themes\Default\admin\css\Default.css`&#x20;
* If you've made changes to any of the default files in the following folders (e.g. `*.aspx`, `*.css`, `*.resx` files), make a backup of the existing files prior to the upgrade and manually re-apply these changes to the corresponding version 9.x.x files:
  * `\wfgen`
  * `\wfgen\App_Themes`
  * `\wfgen\App_Data\Templates\Emails`
  * `\wfgen\App_Data\Templates\Forms`
  * `\wfgen\App_Data\Templates\Processes`
    {% endhint %}

## Update WorkflowGen Windows Services files

### Delete deprecated DLL file

Delete the deprecated `DRIVE:\Program Files\Advantys\WorkflowGen\Services\bin\EAGetMail40.dll` file.

### Overwrite the WorkflowGen Windows Services folder

Overwrite the contents of your WorkflowGen Windows Services folder with the contents of `Update\Program Files\Advantys\WorkflowGen`. By default, the suggested physical path is `DRIVE:\Program Files\Advantys\WorkflowGen`.

{% hint style="danger" %}
Do **NOT** copy and overwrite your existing `DRIVE:\Program Files\Advantys\WorkflowGen\Services\bin\*.config` files.
{% endhint %}

## Update Node.js program files

Copy `node.exe.config` and `trace.config` (located in `Update\Program Files\nodejs`) to `DRIVE:\Program Files\nodejs`.

{% hint style="warning" %}
If there's already a `node.exe.config` file in the `DRIVE:\Program Files\nodejs` folder, **do not overwrite it**. Instead, add the following to the existing file's `<configuration>` node:

```xml
<runtime>
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
        <dependentAssembly>
            <assemblyIdentity name="Newtonsoft.Json" publicKeyToken="30ad4fe6b2a6aeed" culture="neutral" />
            <bindingRedirect oldVersion="0.0.0.0-13.0.0.0" newVersion="13.0.0.0" />
        </dependentAssembly>
    </assemblyBinding>
</runtime>
<system.diagnostics configSource="trace.config" />
```

{% endhint %}

        </dependentAssembly>
    </assemblyBinding>
</runtime>
```

## Update the root web configuration file

{% hint style="warning" %}
This step is **mandatory** when upgrading to version 9.2.2 (9.2 Beta 3) or later, including if you're upgrading from version 9.2.0 (9.2 Beta 1) or 9.2.1 (9.2 Beta 2) and previously updated the root `web.config` file when you upgraded to that version.
{% endhint %}

You must update your site's root `web.config` file with the new URL Rewrite rules.

First, make sure the [URL Rewrite](https://www.iis.net/downloads/microsoft/url-rewrite) tool is installed on your WorkflowGen server.

There are two sample files provided in the installation pack.

* If your WorkflowGen site uses the `/wfgen` path in its URL (e.g. `https://yoursite/wfgen`), refer to the `Inetpub\wwwroot\web.config` (in the manual installation pack) or `Inetpub\wwwroot\web.config.sample` sample file (in the update pack) for the new rules.
* If your WorkflowGen site does NOT use the `/wfgen` path in its URL (e.g. `https://yoursite`), refer to the `Inetpub\wwwroot\web.config.without-wfgen` sample file for the new rules.

## Update the `login.aspx` sample file (custom authentication only)

As of WorkflowGen 9.2.0, If you're using **custom form authentication** with a login page created based on the provided `/wfgen/login.aspx` sample template, you need to update the login page file. To do this:

1. Open your WorkflowGen site's `/wfgen/login.aspx` file (which might have been renamed).
2. Replace the `redirectToUrl = "/wfgen/show.aspx?QUERY=WELCOME";` line with `redirectToUrl = "/wfgen/dashboard";`.

## Update Form Designer webforms for versions 8 and later

As of WorkflowGen version 8, the `WorkflowGen.My.Web.UI.WebControls.dll` assembly has been merged into `WorkflowGen.My.dll`. This breaking change impacts webforms created in the Form Designer and the webforms' `\bin` folders, so you must perform one of the following procedures:&#x20;

### Method 1: Use the provided PowerShell script

Run the `\update\configuration\update-webforms-wfg-my-assembly.ps1` script in PowerShell inside the `\wfgen\wfapps\webforms\` folder. This will automatically update your ASPX webforms and delete deprecated files and folders.

{% hint style="warning" %}
This script requires **PowerShell version 7.0 or later**.

It will update all `.aspx` files located in the `\webforms` folder, including those not managed by the Form Designer. If you have custom webforms in this folder that use another version of `WorkflowGen.My.dll`, then you should skip the changes to these `.aspx` files. You can do this by moving these files to a temporary folder before running the script, and then copying them back to the original folder.
{% endhint %}

#### 📌 Usage example

```bash
.\update-webforms-wfg-my-assembly.ps1 -Path "c:\inetpub\wwwroot\wfgen\wfapps\webforms" -Verbose
```

### Method 2: Manually

1. Delete the following files and folders from the`\wfgen\wfapps\webforms\bin\` folder:
   * `WorkflowGen.My.Web.UI.WebControls.dll`
   * `WorkflowGen.My.Web.Handlers.dll`
   * `\de`
   * `\fr`
   * `\hu`
   * `\pl`
2. Upgrade each of your webforms created in the Form Designer, either by re-saving them or by manually replacing the `<%@ Register Assembly="WorkflowGen.My.Web.UI.WebControls" ... %>` tag with `<%@ Register Assembly="WorkflowGen.My" ... %>` inside each of your `.aspx` files.

## Update the GraphQL and webhooks configuration files

In the `\wfgen\graphql\web.config` and `\wfgen\hooks\web.config` files, add the following to `<system.webServer>`:

```markup
<httpErrors existingResponse="PassThrough" errorMode="Detailed"></httpErrors>
```

## Upgrade the WorkflowGen database

Run the SQL scripts listed below in order, starting with your current version of WorkflowGen.

{% hint style="warning" %}
This section has been divided to provide a quicker reference for clients upgrading from **version 8.0.0 and later**. If you're upgrading from **version 7.22.15 or earlier**, see the [WorkflowGen Legacy Upgrade](https://docs.workflowgen.com/upgrade/9.3.0/workflowgen-upgrade/legacy-upgrade) section and run the required database update scripts based on the version from which you're upgrading, then return to this section and continue with the rest of the required scripts.
{% endhint %}

{% hint style="info" %}
Oracle database is no longer supported as of WorkflowGen 7.16.0.
{% endhint %}

## Configure IIS

{% hint style="warning" %}
Domain users and the Windows accounts used to run the WorkflowGen IIS application pool and Engine service must have read and write permissions for the `\wfgen\app_data` folder.
{% endhint %}

### Update or create the application pool in .NET 4

The WorkflowGen website and web applications must now use an application pool in .NET 4. If this hasn't already been configured, do the following:

1. Install .NET Framework 4 on the server, if it's not already installed.<br>
2. Update the existing application pool or create a new application pool using .NET Framework 4 for:
   * the WorkflowGen website
   * `\wfgen`
   * `\wfgen\wfapps\webforms` (create this IIS web application if it isn’t already created)
   * `\wfgen\ws` <br>
3. If your application pool is set to use **Classic Managed Pipeline Mode**, make sure ASP.NET v4.0.30319 is set to `Allowed` in the IIS manager **ISAPI and CGI Restrictions** list.

## WorkflowGen Node.js-based web applications

To use the GraphQL, incoming webhooks, OpenID Connect Auth, and SCIM APIs, you must first install the following requirements:

* [Node.js v22.20.0 LTS](https://nodejs.org/download/release/v22.20.0/)
* [iisnode](https://github.com/Azure/iisnode/releases/tag/v0.2.21)
* [IIS URL Rewrite](https://www.iis.net/downloads/microsoft/url-rewrite)
* [Visual C++ Redistributable](https://support.microsoft.com/en-us/help/2977003/the-latest-supported-visual-c-downloads)\
  ✏️ **Note:** This library is required if you encounter the error `The specified module could not be found` regarding the `edge` and `edge-js` libraries when accessing the `/wfgen/graphql`, `/wfgen/hooks`, or `/wfgen/scim` web apps.

{% hint style="info" %}

* Delete each Node.js-based application's `node_modules` folder (located under `\wfgen\auth`, `\wfgen\graphql`, `\wfgen\hooks`, and `\wfgen\scim`) before copying the files from the upgrade pack.
* After enabling GraphQL, incoming webhooks, OpenID Connect Auth, or SCIM, the WorkflowGen DLLs will be in use by Node.js, so they'll be locked from being updated. In order to update the DLLs, it's necessary to stop IIS.
  {% endhint %}

### To enable WorkflowGen GraphQL:

1. In IIS, convert `/wfgen/graphql` to an application with a .NET 4 application pool (integrated pipeline).<br>
2. Configure the GraphQL application authentication mode:
   * **For Basic authentication:** Enable Basic authentication.
   * **For WorkflowGen Applicative authentication:**
     * Make sure the `/wfgen` web application already has WorkflowGen Applicative authentication enabled.
     * Enable Anonymous authentication.<br>

2. In IIS, convert `/wfgen/hooks` to an application with a .NET 4 application pool (integrated pipeline), and configure the hook application in **Anonymous** authentication mode.

{% hint style="info" %}
If your WorkflowGen is configured to use WorkflowGen Applicative authentication or a custom authentication, you must remove the authentication module from the `/hooks/web.config` file as follows:<br>

**For WorkflowGen Applicative authentication:**

```html
<location path="hooks" inheritInChildApplications="false">
    <system.webServer>
        <modules>
            <remove name="ApplicationSecurityAuthenticationModule" />
        </modules>
    </system.webServer>
</location>
```

\
**For Custom authentication:**

```html
<location path="hooks" inheritInChildApplications="false">
    <system.webServer>
        <modules>
            <remove name="MyCustomAuthModule" />
        </modules>
    </system.webServer>
</location>
```

{% endhint %}
