[keycloak-user] how to clone a realm?

Hi, I am using keycloak for a multi tenant/multi realm scenario. In all my realms the clients/roles/password policies/groups/authentication/token settings etc are same. So my idea is to create a template realm and clone it to a new realm every time i want to provision a new tenant. I tried using the import/export option, but was not successful. I even tried remvoign all the ids /container id fields from the exported json and changed the realm namesand was unsuccessful again. Any idea how to clone a realm? Looks like import/export was built for replicating/duplicating the data in another keycloak/database instance, and not suitable for cloning /creating a new realm. Any idea how i can create a new realm with defined set of clients, user policies, mappers, authentication settings, flows, token settings and roles? Regards,Madhu
