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