The reason being:
I have many workflows that have a powershell host variable coded as an attribute. As we upgrade vRO, those hardcoded attribute values are not brought over. So I am going to have to go in manually and point them to our new PS host.
I already have developed a workflow to grab all workflows that have an attribute with the Powershell-Host type.
I have searched all through the API and online, and I cannot determine if it is possible to also change these attributes to the new value via a workflow.
