There are situations where you may want to copy FlexDeploy data from one environment to another. There are a few scenarios described below.
Another situation is for isolated networking environments.
If there is a distinct break between your prod and non-prod environments you may need to have 2 FlexDeploy servers, one for builds and deployments to the lower environments, and another that receives the builds from the first FlexDeploy server as imports and then deploys to the prod environment. See the isolated networking documentation to learn about that.
