In the context of the Dynatrace OneAgent, what should be done before performing any uninstallation?

Before performing any uninstallation of the Dynatrace OneAgent, it is crucial to perform a backup of essential files. This step ensures that any important data related to monitoring, configuration, or performance insights is preserved. Uninstallation may lead to loss of custom settings or collected performance metrics that could be valuable for future reference or troubleshooting. By backing up these files, users can revert to their previous configurations or recover lost data if necessary.

Taking this precaution is a standard best practice in IT operations, as it safeguards against unexpected complications that could arise during the uninstallation process. While notifying the server administrator, checking for software updates, and updating configuration files have their own importance, the primary concern prior to uninstallation is data preservation.
