Leaving a Farm


Updated: August 8, 2012

Workflow Manager Configuration Wizard provides a way for you to remove a server on which you have installed Workflow Manager from a farm.

Use the following procedure to leave a farm.

  1. When the Workflow Manager Configuration Wizard page appears, click Leave Farm. The Leave Farm page appears.


  2. Under Farm Management Database the name of the SQL Server farm management database instance for both Workflow Manager and Service Bus farms appears. You do not need to provide input at this point.

  3. Click the Apply link to approve the listed options, specify the farm, and to remove the server from the farm, or click the Back link to return to the welcome screen.

    The wizard displays the Configuration progress screen, which shows the progress of the deletion operation and the details of the current deletion operation in the Details list. If any errors occur during installation, you can click the View log link to see which installation step caused the error.

When you leave a farm, the uninstaller leaves any certificates that you installed on the machine. If you want to remove those certificates, you must do so manually.


The farm management database instance and name come from the registry. They are removed and services cleaned up from the computer even if the connection with SQL Server is down. To clean up the entry from SQL Server, you should use the Remove-WFHost and Remove-SBHost cmdlets as described in Configuring Workflow Manager 1.0 using PowerShell.

Removing a server from a farm is essential when you need to rename a machine or to reduce a farm to a single machine.

To rename a machine that belongs to a farm:

  1. Remove the machine from the farm.

  2. Rename the server

  3. Add the computer back to the farm as described in Joining an Existing Farm.

To reduce the farm to a single computer farm:

  1. Remove all the computers from the farm.

  2. Add the computer you want to be part of the farm.


When reducing the farm to a single computer, it is important to remove all of the computers from the farm, and add the single computer back.
