Important notices

  • You must upgrade to VidyoGateway version 3.5.2 from VidyoGateway version 3.5.1. Therefore, if you have a VidyoGateway version earlier than 3.5.1, you must first upgrade to 3.5.1 and then upgrade to 3.5.2.
  • Additionally, you can refer to the Upgrade Steps Lookup Tool article for information on how to upgrade to VidyoGateway version 3.5.2 from the version you are currently running. This article lists the steps you need to take for your particular version, including which Security Updates you may or may not need to install.
  • Starting with version 3.3.2, the VidyoGateway VE enforces capacity based on CPU reservation, not Virtual Machine configuration. If there is no resource reservation or minimal reservation, the capacity will default to one video call or ten audio-only calls.
  • VidyoGateway VE version 3.3.x uses more memory in order to run more efficiently than older versions of VidyoGateway VE, and therefore requires a minimum of 4 GB of memory. Because previous versions required less memory, you may need to increase the memory allocation on your VidyoGateway Virtual Machine before upgrading.
