Hello @DGuillory ,
Thanks for posting the question and welcome to Microsoft Q & A .
Let me start with saying that one our side we do not have the Netsuite environment and i will try to share my part . Since you mentioned of that you were using the SSIS package . We can do a try to evaluate the lift and shift option , please do read about that more here . https://learn.microsoft.com/en-us/sql/integration-services/lift-shift/ssis-azure-lift-shift-ssis-packages-overview?view=sql-server-ver15#provision-ssis-on-azure
Also just in case if you are trying to move the ETL logic to Azure data factory and since you mentioned that the current setup works on ODBC drivers , you can read this . https://learn.microsoft.com/en-us/azure/data-factory/connector-odbc .
Thanks Himanshu
