I spent hours trying to figure out why setting absolute path to:

```
dbms.active_database = my_db/data/graph.db

```

in `neo4j.conf` file 

* it was resulting in an empty db.

It turns out that the db I created on laptop, on *mac*, does not have a file named "`graph.db`". In fact, I cannot locate which is the db file: see folder structure below.

The configuration file on mac does not have any "`dbms.active_database`" variable nor "`dbms.directories.data`" which I see on ubuntu.

The structure of the db I populated on mac misses a file "graph.db".

This is my\_db folder structure:

I want to copy it on a ubuntu machine, in a custom folder.
Could you explain the differences on mac and ubuntu, to make it compatible?
Should I create my db again on the new machine?
