How do I ID plugin that installed workflows in sandbox

[Fredy Voke]

Hi Team,

While I have captured the Workflows in sandbox update set that I can export to xml or move to DEV, How can I possibly ID the plugin that installed the 4 workflows to get all related objects? 

Pls note - This installation for these 4 workflows was done since 2014. Kindly assist, Thanks All

First - how do you know there are plugins missing?

I could not see them in Dev, Dev have the item Designer module, just not the workflows.
