Export and Import Graylog configuration

[hubs]

I have just moved my Graylog from one ubuntu installation to another. I followed this guide

Exporting Graylog's Configuration for later use

You’d have to export the MongoDB database of Graylog for that and import it into the MongoDB database of your new Graylog cluster. https://docs.mongodb.com/manual/core/backups/index.html https://docs.mongodb.com/manual/reference/program/mongoexport/ https://docs.mongodb.com/manual/reference/program/mongoimport/

Four main things to do

1. Data base dump / export
2. Export / copy graylog config file to new server
3. Export / copy node_id_file to the new server
4. Date base import

Also if your using TLS dont forget to import your certs to the java key store.

I found, as the default installation has the sidecar user already I had to delete it and re-import again so I didn’t lose all my authentication tokens, I also had to add the admin role back to my admin users.

Export / dump command used
mongodump --db graylog --out /home/username/graylog_backup

Restore command used
sudo mongorestore /home/username/graylog_backup

Good luck
