# RPC copy-one-to-one

This RPC is used to perform operations with a configuration from a single source path to a single target path.

RPC input contains the following:

type of operation: merge or replace
type of source datastore: CONFIGURATION or OPERATIONAL
type of target datastore: CONFIGURATION or OPERATIONAL
source path in RFC-8040 URI format
target path in RFC-8040 URI format (target path denotes parent entities under which the configuration is copied)

Target datastore is an optional input field. By default, it is the same as the source datastore. All other fields are mandatory.

RPC output describes the result of the operation. If the RPC fails, no changes are made to the target datastore.

# RPC examples

# Successful example

This example demonstrates how to copy the entire org:orgs container from dev01 to the dev02 node under the uniconfig topology using the replace operation.

# Failed example

This example shows a failed copy-one-to-one operation.

RPC input contains the source datastore (same as the target datastore), merge operation, source path, and target path. The target path is invalid because it does not contain the org:orgs container in the schema tree.
