Conducting comprehensive testing of the Tableau Server on Linux, including data source connections and performance benchmarks Comprehensive testing is essential to ensure that the Tableau Server maintains its performance and stability in the new Linux environment, including verifying data connections and performance standards. Option A is incorrect because neglecting the testing of data connections can lead to critical issues post-migration. Option C is incorrect as only transferring frequently used dashboards does not address the overall stability and performance of the server. Option D is incorrect because changing the database platform is not necessarily required for a migration from Windows to Linux and could introduce unnecessary complexities.
