Upgrade to vRealize Orchestrator 7.6 (vRO) - Empty workflow output


Over the past few weeks I had to update quite a few instances of vRealize Orchestrator to version 7.6, where I experienced that upgraded instances do not show any workflow logs, or values anymore. My first thought was that the workflow was no longer executed, but actually it proofed to be a display problem in the vRealize Orchestrator Client. While talking to a few friends working near the product I got some guidance on how to potentially solve the issue...

The approach I received from VMware support was to manually move my workflows etc. from 7.5 to 7.6 instead of upgrading, which was why I researched the following solution.

However be warned: This is not an official supported solution, while I don't see any issues with it I can't guarantee that you are still supported afterwards.


  1. Login at the console or via SSH into your vRealize Orchestrator appliance with root credentials.
  2. Stop the Orchestrator Service

    service vco-server stop
  3. Remove all lucene log files

    rm -rf /var/log/vco/app-server/scripting.log_lucene*
  4. Start the orchestrator service

    service vco-server start
  5. Logout from the console / ssh session

Everything should be good again.
