Brownfield Fabric Service Overview

In a Brownfield deployment, the legacy software coexists with the new software.

The Brownfield Fabric Service provides the following functionality:

• Ability to migrate the Fabric deployed through an older version of EFA to a newer version of EFA. For instance, if an older EFA server is dismantled, and a newer EFA version or the same EFA version is installed on a different server.
• Ability to migrate from EFA on the TPVM to EFA on an external server.

With this feature, you can migrate the Fabric being configured fully or partially through the use of the SLX CLI or out-of-band means, provided there are no conflicts with EFA Fabric settings. Brownfield deployments are not supported for Tenant Services. The Fabric Service learns and fetches the configuration on the devices through the Inventory Service, performs validation checks, and generates appropriate errors for deviations in the configuration.
