Multinode Configuration Management

Config Synchronization

The config synchronization feature supports simple configuration management across an enterprise without requiring you to deploy the systems as a cluster. You synchronize a partial configuration from the running configuration on the source system to the running configuration on one or more target systems.

  1. Log into the nSA as a Tenant Admin.

  2. From the ICS menu, click Gateways, then click Multinode Configuration and then select Config Synchronization.

    • Successful - Configuration import successful on ICS gateway
