SharePoint 2013: How to fully uninstall Workflow Manager 1.0

Introduction

This posting walks through the process of completely removing the Workflow Manager 1.0 subsystem (and related components) from a SharePoint 2013 farm.  All references used in developing this procedure are listed below.

NOTE: completing this process will not remove any 2013 workflows that have been created and deployed to the target SharePoint 2013 farm.  2013 workflows are stored in the appropriate content databases, just as 2010 workflows are.  Restoring your 2013 workflows is easily accomplished using Designer 2013.  See SharePoint 2013: how to restore Workflow Manager 1.0 workflows in the event of a disaster  for details.

Discussion

The Workflow Manager 1.0 subsystem, when fully installed to a SharePoint 2013 farm, consists of the following components:

• Databases:
• SbGatewayDatabase
• SbManagement
• SbMessageContainer01
• WFInstanceManagement
• WFManagement
• WFResourceAutomation
• Software:
• Microsoft Web Platform Installer 4.6
• Service Bus 1.0
• Windows Fabric
• Workflow Manager 1.0
• Workflow Manager Client 1.0
• SharePoint Service Applications
• Workflow Service Application Proxy
• Application Folders
• Application Folder: C:\Program Files\Workflow Manager\
• Registry Keys
• HKLM\SOFTWARE\Microsoft\Workflow Manager
• HKLM\Software\Microsoft\Service Bus
• Certificates
• WorkflowOutbound
• SSL
• Encryption (can be the same certificate as used for SSL)

All of these components, except for the Microsoft Web Platform Installer 4.6, registry keys and certificates, must be removed.  The following procedure shows you how.

Notes

• Uninstallation took approximately one hour, including taking screen shots and writing notes of the process.
• The uninstallation was undertaken to address an issue that presented after installing the September 2014 CU.  The issue resulted in the Workflow Manager Backend service repeatedly stopping and then restarting.  This seemed to have caused all 2013 workflows to perform sluggishly or not at all.  After working through several possible solutions, the remaining one was to uninstall and then re-install the entire Workflow Manager 1.0 subsystem.  This resolved the problem.
