I'm glad to hear that the platform solution works well. I should try it too. But need the actual version of IRIS, becouse to control what is active across environments - it's very important, I believe

That's what I was thinking when I described these options: 4, it's just not an automated version of 2. I would use copy and paste or some merging to add the same items across Productions. And automate merging of content while keeping individual settings - it's the obvious next step, right? 

Yes, it's a good solution if we want to keep a different structure of Productions (to keep development stuff on DEV Production). But I believe it's not a big problem, I'm just committing all new services in a disabled state (actually, they're disabled automatically). Therefore, stuff under development, yeah, can get to PROD but in an inactive state.

Just thinking out loud, so to speak...

When can we see the result? 🙂
