Upgrade package download instructions:
Please contact us at support@fudosecurity.com to receive proper upgrade package for your Fudo current software version.

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

  1. Make sure your Fudo is not undergoing any system-wide process, like a storage matrix rebuild or is under high load.
  2. In cluster configuration, make sure all nodes are synchronized and upgrade the slave node first.
  3. Make sure you have active Premium or Standard Support maintenance contract.

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, start the upgrade from the Slave node, then move onto upgrading the Master node. 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 upgrade package 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.

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. To do so, click user menu on the top, select ‘Restart’ and select previous system revision from the drop-down list.
Please keep in mind any session recordings performed on never version will be lost upon upgrade rollback execution.
