If a Dynatrace OneAgent is upgraded, what type of configuration file may be found?

When a Dynatrace OneAgent is upgraded, the configuration file that may be found is _migratedloganalytics.conf.json. This file typically contains settings or preferences that have been transferred or adjusted during the upgrade process, ensuring that the new version of the OneAgent has the necessary configurations to operate with previously established parameters.

This process is crucial because upgrades often involve changes to functionality or structure, and having a migration log helps maintain consistency in how the agent collects and reports data. By retaining previous configurations, it minimizes the disruption of service and ensures that any historical data can be accurately interpreted moving forward.

The other choices reflect different scenarios that do not specifically apply to the process of upgrading OneAgent. For instance, files such as _newconfig.log.json or _backupconfig.json may suggest new settings created or backups made, but they do not specifically address the migration of log analytics during an upgrade. Similarly, _defaultconfig.json implies a reset to default settings rather than providing continuity through the upgrade process.
