Gotcha! that title makes no sense.
My preparation would all be in my head for this data move from Microsoft SQL Server 2019 to MySQL 8.0. Accessing the former from SQL Server Management Studio and the later through My Workbench.
The cloud is not a new operating system.
The data would NOT be “uploaded”, just copied from a remote Windows SQL Server to a remote Linux MySQL server. And that sounds like a job for SSIS. (preparation complete 🙂 )
