Version RA 5.5.x
What do I want?To export all the environments' parameters through REST API or CLI, just like we can do it in the UI exporting the XML manifest.
The output format could be JSON or XML.
Why do I need it for?To track (version) the environments' parameters over the time.
You can try using the following URL http://<RASERVER>:<RA PORT>/datamanagement/a/environments/<ENV ID]/parameters
Exactly what I was looking for.
