True ETL Tools
If you need more than just to copy data from Dynamics 365 to MySQL, you may use Skyvia's powerful ETL functionality for Dynamics 365 and MySQL integration. Skyvia's Import tool will correctly extract Dynamics 365 data, transform it, and load to MySQL when MySQL tables have different structure than Dynamics 365 objects. Moreover, Skyvia Import allows loading data in any direction, supporting Reverse ETL scenario.
For more complex cases, you can use Data Flow and Control Flow tools. They are designer-based solutions for creating complex data pipelines, involving not only Dynamics 365 and MySQL connectors, but any number of connectors in one integration. With these tools you can automate data workflows, involving custom logic, complex multistage transformations, combine data from different sources, load them into multiple destinations at once and many more.
