Before you upgrade

There are a few things that need to be verified before this upgrade can be applied.

  1. Make sure your Fudo system is at least version 3.4-xxxxx LTS. If you have an older system version, please contact us and we will help you with the upgrade process.
  2. Make sure your Fudo is not undergoing any system-wide process, like a storage matrix rebuild or is under high load.
  3. In cluster mode please make sure cluster state is in sync. Start upgrade from cluster slave.
  4. Please make sure you have active maintenance contract: Premium or Standard Support.

How to upgrade your Fudo:

  1. Login to your Fudo and from the menu on the left hand side select ‘System’, then the ‘Upgrade’ tab
  2. If your Fudo is running in a cluster please start the upgrade from the Slave system, then move to the Master. When both systems are on the same Fudo version cluster communication will be restored.
  3. Select “Upload” from the top left side and upload the previously downloaded and unzipped fudo-3.9-xxxx.upg file
  4. Select “Run Check” to determine if your upgrade file is correct and can be applied to existing Fudo configuration. Refresh your browser window to see “Upgrade check” current progress.
  5. Upon a successful “Run Check” result, upgrade your Fudo by using the “Upgrade” button. Upon system restart all active sessions will be terminated.

In case of an unsuccessful check do not upgrade your system, double check your upgrade file checksum. If you encounter any problems, get in touch with us and we will assist you.

Rollback option:

After the new Fudo version is booted up, in System -> Upgrade tab you will see a button entitled “Remove upgrade snapshot”. If you are experiencing issues with newly installed version, you have an option to roll back to the previous version of Fudo system previously running on this machine. Please keep in mind any session recordings performed on never version will be lost upon upgrade rollback execution.
