WorkflowGen 8.1.3 Upgrade
Overview
The following procedures apply to the WorkflowGen 8.1.3 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 is not the standard DRIVE:\Inetpub\wwwroot\wfgen\App_Data 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 these 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
2.Delete the following files and folders from the \wfgen\hooks folder:
\controllers
\models
\node_modules
\services

server.js
upload.js
3.Delete the following files and folders from the \wfgen\auth folder:
\controllers
\models

\static
\utils
config.js
config.production.js
server.js
4.Delete the following files and folders from the \wfgen\scim folder:
\controllers
\models
\node_modules
\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

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.
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
If you have 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 8.x.x files:
\wfgen
\wfgen\App_Themes
\wfgen\App_Data\Templates\Emails
\wfgen\App_Data\Templates\Forms
\wfgen\App_Data\Templates\Processes
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.
Do NOT copy and overwrite your existing DRIVE:\Program Files\Advantys\WorkflowGen\Services\bin\*.config files.
Update Node.js program files
Copy node.exe.config and trace.config (located in Update\Program Files\nodejs) to DRIVE:\Program Files\nodejs.
If there is 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:
<runtime>
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
        <dependentAssembly>
            <assemblyIdentity name="Newtonsoft.Json" publicKeyToken="30ad4fe6b2a6aeed" culture="neutral" />
            <bindingRedirect oldVersion="0.0.0.0-12.0.0.0" newVersion="12.0.0.0" />
        </dependentAssembly>
    </assemblyBinding>
</runtime>
<system.diagnostics configSource="trace.config" />
Update configuration files
This section contains configuration parameter changes to be applied based on the version of WorkflowGen from which you are upgrading.
📌 Examples
When upgrading to version 8.1.2 from version 8.0.1, apply the changes in the When upgrading from version 8.0.1 and earlier, When upgrading from version 8.0.2 and earlier, When upgrading from version 8.0.7 and earlier, When upgrading from version 8.0.8 and earlier, and When upgrading from version 8.1.0 and earlier sections.
When upgrading to version 8.1.3 from version 8.1.2, apply the changes in the When upgrading from version 8.1.2 and earlier section only.
You must remove the xmlns attribute from the web configuration file regardless of the version from which you are upgrading. See Remove the xmlns attribute for instructions on how to do this.
