mutation {
  export(input: { format: "rdf" }) {
    response {
      message
      code
    }
  }
}
curl http://localhost:8080/admin --silent --request POST --header "Content-Type: application/graphql" --upload-file export.gql

and then import data to new dgraph v21.03 by follow command

dgraph bulk --http dgraph_alpha:8000 --zero=dgraph_zero:5080 -s /dgraph/export/g01.schema.gz -f /dgraph/export/g01.rdf.gz -g /dgraph/export/g01.gql_schema.gz
