WorkflowGen 7.16.1 Upgrade

Overview
The following procedures apply to the WorkflowGen 7.16.1 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 the existing DRIVE:\Inetpub\wwwroot\wfgen\hooks\test folder before copying the files from the upgrade pack, since the upgrade pack contains a newer version.

Copy and overwrite with 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.
Important notes
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 7.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
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.
Important: Do NOT copy and overwrite your existing DRIVE:\Program Files\Advantys\WorkflowGen\Services\bin\*.config files.
Update the web configuration file
This section contains configuration parameter changes to be applied based on the version of WorkflowGen from which you are upgrading. For example:
When upgrading to version 7.16.1 from version 7.10.0, apply the changes in the When upgrading from version 7.14.3 and earlier, When upgrading from version 7.14.6 and earlier, When upgrading from version 7.15.2 and earlier, When upgrading from version 7.15.4 and earlier, and When upgrading from version 7.15.5 and earlier sections.

When upgrading to version 7.16.1 from version 7.16.0, there are no changes to apply to the configuration file.
Important: 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.

   <add name="iisnode" path="dist/server.js" verb="*" modules="iisnode"/>
</handlers>
​
<rewrite>
   <rules>
      <rule name="DynamicContent">

Configure IIS
Note: 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.
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 has not already been configured, do the following:
Install .NET Framework 4 on the server, if not already installed.

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 

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.
Restart the WorkflowGen server
Reboot your WorkflowGen web server.
New location of workflow application temporary and log files
The following workflow applications store their files in these new locations:
EFORMASPX: \wfgen\App_Data\Files\EFormAspx 

XMLTODATABASE: \wfgen\App_Data\LogFiles\XmlToDatabase 

XMLTRANS: \wfgen\App_Data\Files\XmlTrans and \wfgen\App_Data\LogFiles\XmlTrans
