# RPC replace-config-with-operational

RPC replaces the UniConfig topology nodes in the Config datastore with UniConfig topology nodes from the Operational datastore. The RPC input contains a list of the UniConfig nodes to replace from the Operational to the Config datastore of the UniConfig transaction. Output of the RPC describes the result of the operation and matches all input nodes. If RPC is invoked with empty list of target nodes, operation will be invoked for all nodes modified in the UniConfig transaction. If one node failed for any reason, RPC will fail entirely.

# RPC Examples

# Successful Example

RPC replace-config-with-operational input has 2 target nodes and the RPC output contains the result of the operation.

# Failed Example

If the RPC input does not contain the target nodes and there weren't any touched nodes, the request will result in an error.
