About software updates and the multilink feature

When you update your deployment from Cyber Recovery version 19.13 or earlier to Cyber Recovery version 19.14 and CyberSense version 8.2 or later, the software creates default multilink definitions.

Follow the steps in the PowerProtect Cyber Recovery 19.14 Release Notes to create DD Boost users before the update to ensure that the default links are in the Active state. Analyze schedules on existing Cyber Recovery deployments can then continue to run as they did before the update.

NOTE:
  • Previous combinations of Cyber Recovery and CyberSense versions enabled you to create alternate storage interfaces for on-demand and scheduled Analyze operations. If the Cyber Recovery software detects alternate storage interfaces, it creates default multilink definitions that map to these alternate storage interfaces.
  • Multilink configurations for Cyber Recovery version 19.13 and later with CyberSense version 8.2 and later require that CyberSense and the DD are on the same subnet. If CyberSense and the DD system are on different subnets, the multilink configurations do not work. If you cannot change the network configuration to use the same subnet, avoid updating to the combination of Cyber Recovery version 19.13 and later with CyberSense version 8.2 and later or contact Cyber Recovery Support for a workaround.
  • If CyberSense is updated after the Cyber Recovery update, the multilink auto configurations occur as soon the Cyber Recovery software detects CyberSense version 8.2 or later.
  • If you do not perform the preupdate steps to create at least one DD Boost user, which are described in the PowerProtect Cyber Recovery 19.14 Release Notes, then you must assign a DD Boost user to the default multilink configuration before the link becomes Active.
