I have not upgraded Graylog in a while…
Is there or has anyone made a step-by-step guide on doing the actual upgrade to 3.0? I have looked at Graylog’s 3.0 upgrade document and it seems to be more with potential changes and things to keep in mind rather than an upgrade guide. Any thoughts?
Upgrade link I looked at: https://docs.graylog.org/en/3.0/pages/upgrade/graylog-3.0.html
