When the Password Manager settings are exported both the functional (Workflows, Password Policies etc) settings and the technical (Domain Connections, User & Helpdesk scopes) settings are all exported together.
It is sometimes desirable to have the ability to export either the functional or the technical but not both.
It is not possible to export them separately.
However it is possible to export each individual workflow from the Admin site and then import them into the new instance.
This means that the functional as opposed to the technical parts of Password Manager can be exported.
If Password Policies are configured then they can also be exported from the primary instance and then import them into a different instance.
