Flow Designer - Moving in udpate sets issue

[Sandy7]

Hello -

I created a flow in Flow Designer. An action is tied to it as well. 

I was able to move the Flow itself in an update set, but the Action did not get moved with the update set. I see the entry for the action, but when I open the action it says Step Definition not found. 

I even went to the sys_hub_flow table and exported the xml & imported to the other instance and I am still having the same issue.

Does anyone know why i can move the Flow itself but not the Action?

Greetings Sandy,

 Check to make sure that the target instance has exactly the same plugins for IntegrationHub. If it is exactly the same, then republish the action and flow into an update set, and try moving again.

Thank you - looks like our plugins in our higher instances are the problem.

Thank you for posting this Question and Answer. I ran into a similar Promotion error and it turned out it was one missing Plugin (there were several Plugins the promotion was dependent on, and "seeing" the one missing Plugin was actually a bit challenging - had to work through a process of elimination).
