Question: Is there a way (plugin or tool) to export the data from the database (or database itself) ? I'm looking for this feature as I need to migrate a DB from present host to another one.

Answer: 
You could dump each table and load them through REST interface:

```
curl "http://hosta:8086/db/dbname/series?u=root&p=root&q=select%20*%20from%20series_name%3B" > series_name.json
curl -XPOST -d @series_name.json "http://hostb:8086/db/dbname/series?u=root&p=root"

```

Or, maybe you want to add new host to cluster? It's easy and you'll get master-master replica for free. [Cluster Setup](http://influxdb.com/docs/v0.8/clustering/setup.html)
If you have access to the machine running Influx db I would say use the [influx\_inspect](https://docs.influxdata.com/influxdb/v1.6/tools/influx_inspect/) command. The command is simple and very fast. It will dump your db in [line protocol](https://docs.influxdata.com/influxdb/v1.6/write_protocols/line_protocol_tutorial/). You can then import this dump using [influx -import](https://docs.influxdata.com/influxdb/v1.6/tools/shell/#import-data-from-a-file-with-import) command.
