Hi @jansi rani krishnan ,
you can export the Runbooks in Orchestrator Designer (right-click on Runbook tab) one by one or a folder (right-click on folder) with all Runbooks in the folder.
Copy the export file to the productive Orchestrator server and import.
You are right with export/import the IDs (GUIDs) will change.
