Hello friend I hope you are well to perform the migration of the agents and all the configurations you can follow this guide of our documentation, but maybe you have already seen it?

Also, I leave you other guides that may be helpful

Hi Kumar,

Since you're looking to automate the re-configuration and re-registration process (and the manager has already been created) I believe you're looking for something like this:

#!/bin/bash newip=192.168.43.2 sed -ir "s#<address>.*</address>#<address>$newip</address>#g" /var/ossec/etc/ossec.conf /var/ossec/bin/agent-auth -m $newip systemctl restart wazuh-agent

This assumes you're only using the <global><address> stanza to specify where your agents need to connect to. If your agents also have an <enrollment> section configured then be sure add another sed command to modify the <manager_address> configuration.

Let us know if you have any other questions.

Best regards,

Juan C. Tello
