Conversion errors in SSMA
You may use an SQL Server Migration Assistant (SSMA) for your database migration projects to automate the conversion process. Usually SSMA automatically converts the major part of the source code. But still, your code may cause some sort of errors, needed to be resolved manually. In this case, SSMA generates corresponding error or warning messages, displays them on the screen and adds as the comment to the converted code.
So, to explore the error and warning messages, occurred in your conversion project, just check the bottom part of the application window.
Therefore, SSMA doesn’t provide any suggestions on how you may address the certain error or warning. However, the application estimates the time, required to complete the conversion manually.
