# RPC copy-one-to-one

RPC input contains:

type of operation - 'merge' or 'replace',
type of source datastore - CONFIGURATION / OPERATIONAL,
type of target datastore - CONFIGURATION / OPERATIONAL,
source path in RFC-8040 URI formatting,
target path in RFC-8040 URI formatting (target path denote parent entities under which configuration is copied).

Target datastore is optional input field. By default, it is the same as source datastore. Other input fields are mandatory, so there is forbidden to call RPC with missing mandatory field. Output of RPC describes result of copy to target path operation. If RPC failed for some reason, RPC will be failed and no modification will be done to datastore.

Description of RPC copy-one-to-one is on figure below.

# RPC Examples

# Successful example

The following example demonstrates coping of whole 'org:orgs' container from 'dev01' to 'dev02' node under 'uniconfig' topology. Replace operation is used.

# Failed example

The following example shows failed copy-one-to-one RPC. Input contains specified source datastore (target datastore is the same), merge operation, source path, and target path. In that example target path is invalid, because it doesn't contain 'org:orgs' container in the schema tree.

RPC Request
curl --location --request POST 'http://localhost:8181/rests/operations/subtree-manager:copy-one-to-one' \
--header 'Accept: application/json' \
--header 'Content-Type: application/json' \
--data-raw '{

        "target-path": "/network-topology:network-topology/topology=uniconfig/node=vnf02",
        "operation": "merge"
    }
}'
