Is it possible to upgrade Ubuntu to 16.10 without disturbing the operation of Graylog?
The Graylog version is:
dpkg -l graylog
ii graylog 2.0.2.1 amd64 The full stack of graylog
Is it possible to upgrade Graylog to version 2.4.6 is one step?
The ultimate goal is that also Windows systems log to the Graylog server.
When you upgrade your OS you should just watch to match the java version and that Elasticsearch is running in a compatible version.
Upgrade from 2.0 to 2.4 is not tested in one step - it might work but we only test and support the upgrade from the last stable to the new stable. So you would need to upgrade to 2.1 -> 2.2 -> 2.3 and final to 2.4 following the upgrade nodes in the documentation.
