You will find the page Backup & restore (previously “Snapshots of Config”) under the “Common” Common tab in Kantega SSO Enterprise.
...
You then click “create snapshot”
...
Your snapshot will then show in the list:
...
These snapshots can be found as .zip files in the home folder of your Atlassian server, under kerberos_snapshots
...
You may can for example move this .zip to a new server instancecluster, and add it under a home directory with the exact name kerberos_snapshots.
Please let me know if there is anything else I can help you with, and a config from the production environment can be mirrored in a staging environment.
