Transfer/copy/move my Instant App to a new build

[MikeGarcia]

I have an Instant App which uses the "Interactive Legend" template on an old DEV ArcGIS Enterprise 10.9.1 system and would like to "Move/copy/transfer" it to a new 11.1 system.  

I am unable to find a simple way to export this to a format that is importable into my new system.  The instant app interface allows for Copying, but that does not make a portable file.  

I tried digging into my portal files at ...\ArcGIS\Portal\apps\instant... where I can see the app and copying it into 11.1 at the same location, but that didn't work. 

It sorta looks like a JavaScript 3. app which makes me think it might go into WebAppBuilder, but I would rather build it from scratch in JavaScript 4. than go down the WAB path.

As far as I'm aware Instant apps exist in 11.1 so you could rebuild it from scratch.

If you want to copy it over you could try using a script like this https://github.com/jmirmelstein/ArcGIS-Python-API-Samples/blob/master/Samples/Copy%20Specific%20Item.... I'm not sure if it would work since you're going between enterprise versions.

You could also set up a distributed collaboration between the enterprise versions but that pattern is typically recommended for content promotion rather than migration.

Thank you for the options.  
I was not aware of the py clone_items function, but I sounds like it would be fun to try some time. 

For now, we will rebuild the Instant app in the new Portal.
