You can replicate configurations across clusters of the same or different Access Manager setups.
Scenario 1: Replicating configuration changes between two clusters of the same setup (cluster1 and cluster2):
Export configurations from cluster1. See Exporting Configurations from a Cluster.
Import configurations to cluster2. See Importing Configurations.
Scenario 2: Replicating configuration changes between two different Access Manager setups (setup1 and setup2):
Export the configuration files from setup1. See Exporting Configurations from a Cluster.
Go to setup2 and import the configurations that you exported from setup1. See Importing Configurations.
