I installed graylog more a year ago from OVA image. In the meantime I did several updates successfully. I have now Graylog 2.5.1+34194da on graylog (Oracle Corporation 1.8.0_191 on Linux 4.4.0-97-generic)
with DB : /opt/graylog/elasticsearch/bin/elasticsearch --version
Version: 5.6.13, Build: 4d5320b/2018-10-30T19:05:08.237Z, JVM: 1.8.0_191
Reading the documentation
I see saying:
2.x It is not possible to upgrade previous OVAs to Graylog 3.0.0.
( even I tried, but of course I failed )
Actually a clear statement. But is this a general statement or is simple an automated upgrade not possible ?
If manually possible, is there a description anywhere available ? This doc
describes partly the changes made in the new version and new features it but didn’t give a step-by-step how to do.
Of course I could setup V 3 from OVA again but my “old” graylog got a lot of changes over time. And there are still some questions:
- is there a way to take over all configurations, like all inputs, stream and alerts ?
- what about to take over elasticsearch DB with all the logs from last half year ?
Any feedback is welcome
