cd neo4jtransfer
composer install
./bin/build
./neo4jtransfer.phar help

Commands and arguments

The following commands are available:

The dump command

Dump all nodes and relations from a Neo4j database into a cypher file.

./neo4jtransfer.phar dump --output=default --source-host=neo4j1-prod

Dump command arguments

Run cypher queries from a file.

Import command example

The following command will look for the latest dump corresponding to the neo4j1-prod host (eg. dump-neo4j1-prod-20160615-233212.cypher) and execute the cypher queries within onto the Neo4j database on localhost.

./neo4jtransfer.phar import --input=last:neo4j1-prod

Import command arguments

The direct transfer command

Transfer nodes and relations from one Neo4j database into another without an intermediary dump file.

Direct transfer command example

The following command will transfer all nodes and relations from neo4j1-prod into app1-dev within a single transaction.

./neo4jtransfer.phar direct --source-host=neo4j1-prod --target-host=app1-dev --transactional

Direct transfer command arguments

The transfer command

Transfer nodes and relations from one Neo4j database into another and save all cypher queries to a dump file.

Transfer command example

The following command will transfer all nodes and relations from neo4j1-prod into app1-dev within a single transaction and create a dump file for backup. (eg. dump-neo4j1-prod-20160615-233212.cypher)
