*** Important: Read upgrade instructions and test add-on update before deploying to production *** The Splunk Add-on for Windows 5.0.0 introduced breaking changes. If you are upgrading from a version of the Splunk Add-on for Windows that is earlier than 5.0.0, you must follow the documented upgrade instructions to avoid data loss. A best practice is to test the upgraded version in a non-production environment before deploying to production. Neither the Splunk Add-on for Windows DNS version 1.0.1 nor the Splunk Add-on for Windows Active Directory version 1.0.0 is supported when installed alongside the Splunk Add-on for Windows version 6.0.0. The Splunk Add-on for Windows version 6.0.0 includes the Splunk Add-on for Windows DNS and the Splunk Add-on for Microsoft Active Directory. The Splunk for Microsoft Windows add-on includes predefined inputs to collect data from Windows systems and maps to normalize the data to the Common Information Model.
