[keycloak-user] Complete export of a realm without shutdown

Hello, I need to migrate a realm from a running Keycloak server. I have been looking at the REST API, the command line and finally the startup options. The startup option provide the best way to export a realm but it requires a restart. Am I missing something or is this not yet supported? Would it be possible to use bits and pieces of the command line or REST API to construct a complete export? Kind regards, Bart
