Is there a way to extract or backup parameters set up in Octopus Deploy (version 3 or version 4)? Either thru an Octopus Deploy service (capability) or scripting, not from a backup database.
Could the Octo.exe be your answer?
For example:
octo export --server=https://octopusaddress/api --apiKey=API-XXXXXXXXXX --type=project --name="MyProject" --filePath=MyProject.json
