How uninstall and install workflow manager 1.0 in sharepoint 2013

Question

we have already workflow manager 1.0 installed and processed workflows successfully.

We deleted the site where the workflows are subscribed and the associated workflow scopes status become unregistered. We tried republishing the workflows but still unable to process the workflows.

So we are planning to reinstall the workflow manager.

So so we need to uninstall every component in workflow manager and reinstall them from the beginning or can we specifically uninstall few components and reinstall them ?

Answer 1

I do not think you have to re-install any of your WFM components.

It sounds like you have deleted the site that was used in the SPSite parameter when registering a workflow scope with Register-SPWorkflowService cmdlet.

In that case you have a couple of options to get it re-registered:

• Delete the old scope and re-run the Register-SPWorkflowService cmdlet - Remove Workflow Manager scopes?
• Re-run Register-SPWorkflowService cmdlet but with the -Force parameter
• Re-run Register-SPWorkflowService cmdlet but with a new scope name

Than re-publish your workflow definitions and check that the workflow subscriptions are still there.

There is a similar issue - I think - described here: https://blogs.msdn.microsoft.com/spses/2016/08/09/sharepoint-2013-spd-2013-workflows-are-getting-associated-with-the-list-but-they-arent-starting/

There are couple of steps:

• Delete the Application Proxy from Central admin
• remove the Workflow Manager Cert from the Central admin > maange trust.(if using the SSL connection).
• On WFM server, Runt he wizard and Leave the server from Farm (workflow Manager wizard).
• Delete all accosicated databases.
• Unistall the WFM, Service Bus, WFM Client from the Control panael (add remove program).
• Delete the registry keys (HKLM\Software\Microsoft\Workflow Manager and HKLM\Software\Microsoft\Service Bus)
• Delete the folder.(C:\Program Files\WorkflowManager and Service Bus installs at C:\Program Files\ServiceBus)
