I have SharePoint farm with workflow manager!
We are planning to update our farm with the latest update
Will I need to rerun the register cmdle, after applying the update?
You don’t need to rerun, the Register-SPWorkflowService cmdlet should only be run once for the entire SharePoint farm. Once a SharePoint farm is associated with Workflow Manager the cmdlet does not need to be run again unless you are restoring SharePoint from a backup.
