I assume you mean Migration Assistant? I haven't used it personally but I am sure someone on here will have an opinion once its clear.
You would need an ODBC driver if you wanted to use SSIS to connect to your sybase database. Quickly looking at Migration Assistant it does have a Sybase variant so designed for the job and will create the objects for you.
As SSMA is free I would give it a go. It has all the client tools you need in one package!
