Offline upgrade from 4.13.1 to 4.14.1

[j885...@gmail.com]

Hello! 

1) Could you please provide a comprehensive offline upgrade guide for all-in-one Wazuh from version 4.13.1 to 4.14.1 on Ubuntu server.

I've read through the Offline installation guide, but it only covers fresh install. What I need is an upgrade guide to make sure the upgrade is flawless.

2) Could you provide a guide on how to configure manager to send agent upgrades from manager, that has no connection to the internet. I'm a bit confused about wpk files mentioned in the guide.

Hello,


Download and copy the correct packages for your OS following this link.
https://documentation.wazuh.com/current/installation-guide/packages-list.html

Follow this guide for Wazuh central components upgrade.

Skip the Wazuh repository update part at the start ( part 1 from Preparing the upgrade section)

Follow every step, same as the document.

Only for updating services, use the pre-downloaded packages.


For example, for a Debian-based OS

sudo dpkg -i package-name.deb

If you need further assistance, share with me the OS and OS version of your Wazuh Server.

For the agent upgrade, download the .wpk file from this document and copy it to your manager.

https://documentation.wazuh.com/current/user-manual/agent/agent-management/remote-upgrading/wpk-files/wpk-list.html

And you can do remote upgrades by running a command like this from the Wazuh server.

/var/ossec/bin/agent_upgrade -a 001 -f /home/wazuh/wazuh_agent_v4.14.1_windows.wpk -x upgrade.bat

For Linux agents, use upgrade.sh. to upgrade a Windows agent, you must use upgrade.bat instead of upgrade.sh.

For upgrading the central component, I suggest you perform the upgrade in a test server before doing it in the production environment.

Let me know if you need any further assistance.
