Hey @Deepak Kumar Kalyanum ,
Is the requirement to just migrate SSIS to cloud or even the database to cloud?
If it is complete migration, I would suggest ADF is the best option .
In case if it is just SSIS migration, then please verify whether all transformations of ssis are readily available in ADF as ADF is still evolving. If all are not available then better to leverage SSIS + ADF for easy migration.
