unable to import/export neo4j data between different neo4j instances.

[Bhupesh Goel]

Hi,

I am trying to export and then import neo4j graph data from one db instance to another db instance. 

For exporting data from one DB instance i am executing command "./bin/neo4j-shell -c dump > data.txt" and for importing the exported data in file.txt to another db instance i am executing command "./bin/neo4j-shell -file data.txt" command.

For simplicity the content of data.txt dump file is of the form 

begin

 create (_0 {`name`:"Neo"});

 create (_1 {`app`:"foobar"});

 create (_2 {`app`:"foobar2"});

commit

begin

 create _1-[:`LIKES`]->_0;

 create _2-[:`LIKES`]->_0;

commit

Please note that i manually add semicolons after every statement in above dump.

After i import this form of graph data in data.txt to another fresh instance of neo4j db than what happens is it will create three nodes corresponding to first three lines and then further creates three more empty nodes corresponding to the third and fourth edge. It also creates edge between three empty nodes only. So, the dump of imported data in new db instance will look like 

begin

create (_0 {`name`:"Neo"})

create (_1 {`app`:"foobar"})

create (_2 {`app`:"foobar2"})

create (_3)

create (_4)

create (_5)

create (_6)

create _3-[:`LIKES`]->_4

create _5-[:`LIKES`]->_6

;

commit

Please do let me know what is wrong here and what is best way of importing data from one db to another neo4j db instance?

I added a new export tool to my neo4j-shell-tools, and would love if you could try it out:
