Single Node Upgrade from 4.27 to 4.28¶

This guide will lead you through the steps specific for upgrading a NetEye Single Node installation from version 4.27 to 4.28.

Upgrading a NetEye Single Node takes a nontrivial amount of time. Granted the environment connectivity is seamless, the upgrade procedure may take up to 30 minutes.

Warning

Remember that you must upgrade sequentially without skipping versions, therefore an upgrade to 4.28 is possible only from 4.27; for example, if you have version 4.21, you must first upgrade to the 4.22, then 4.23, and so on.

Breaking Changes¶

Audit Log Retention Policy¶

With the introduction of the Login Auditing for icingaweb2 we also introduced a Retention Policy for the Audit Logs. The default is set to 365 days. To find out more, you can visit The Audit Log Retention Policy

Prerequisites¶

Before starting the upgrade, you should read very carefully the latest release notes on NetEye’s blog and check out the features that will be changed or deprecated after the upgrade.

All NetEye packages installed on a currently running version must be updated according to the update procedure prior to running the upgrade.
NetEye must be up and running in a healthy state.

1. Run the Upgrade¶

To perform the upgrade, run from the command line the following command:

neteye# (nohup neteye upgrade &) && tail --retry -f nohup.out

After the command was executed, the output will inform if the upgrade was successful or not:

In case of successful upgrade you might need to restart NetEye to properly apply the upgrades. If the reboot is not needed, please skip the next step.
In case the command fails refer to the troubleshooting section.

2. Reboot¶

Restart NetEye to apply the upgrades correctly.

neteye# neteye node reboot

3. Additional Tasks¶

In this release, no additional task is required.
