Zero-downtime upgrade makes sure there is no downtime for your production system when BMC performs upgrade of your platform and applications. However, you might observe some issues intermittently, and you should avoid certain operations during the zero downtime upgrade.

Important

You can continue with the transactional user operations during the platform and applications upgrade such as creating tickets, creating tickets through REST APIs, searching tickets, and searching knowledge articles.

During an upgrade, a notification message appears in the BMC Helix Innovation Suite to inform you that the upgrade is in progress.

Limitations and cautions

You might encounter the following issues while an upgrade is in progress:

  • Network connections with AR System server might not work for some time.
  • You might experience slow performance.
  • You might observe the following issues intermittently once during platform restart for a short duration of time:
    • Session timeouts
    • UI errors
    • RSSO authentication failed error
    • 502 Bad Gateway
    • Invalid credentials
    • HTTP ERROR 404 Not Found

If you experience these issues, you can perform a refresh or login to the system and retry the operation after some time.
