Upgrade Graylog from old version

Graylog Central (peer support)

Hello,

I will continue an old project, which has been abandoned for about 2 years about Graylog. He uses the Graylog 2.0.3 in this moment, but I would like to use the latest version of Graylog (2.4.3). It’s possible to upgrade ?

Thanks

Yes, it’s possible to upgrade Graylog 2.0.3 to Graylog 2.4.4 (the latest stable version at the time of writing).

Make sure you thoroughly read the upgrade notes at http://docs.graylog.org/en/2.4/pages/upgrade.html.

Then, depending on how Graylog was originally installed, you can either upgrade the DEB/RPM package (see http://docs.graylog.org/en/2.4/pages/installation/operating_system_packages.html#update-to-latest-version or http://docs.graylog.org/en/2.4/pages/installation/operating_system_packages.html#operating-package-upgrade-rpm-yum-dnf respectively), upgrade the Graylog Omnibus package (see http://docs.graylog.org/en/2.4/pages/configuration/graylog_ctl.html#upgrade-graylog) , or upgrade a manual installation (see http://docs.graylog.org/en/2.4/pages/installation/manual_setup.html).

This being said, if you don’t need the data in your old Graylog cluster, it might be much simpler to delete the existing Graylog cluster and create a completely new installation.

Thanks for your information.

I did not know if it was possible to update directly from 2.0.3 to 2.4.4. (in one try) beacause When I see the documentation about upgrade in 2.4.x it’s write : “You can upgrade from Graylog 2.3.x to Graylog 2.4.x without the need to change the configuration of your Graylog server”

I think of creating a new machine as you suggested, if it’s more easy
