Hi,
We have a 2010 farm with 100+ site collections that use workflows extensively. We're preparing for a 2013 migration and would like to identify all workflows that use custom actions designed with Visual Studio. Unfortunately, these features were scoped at the web app level so I am not aware of way to identify which sites are using the actions. Is there any way to list all workflows that use a specific action via powershell, stsadm or any other methods? Thanks!
