Has anyone used SSIS for legacy data migration into NetSuite? I’m researching solutions for a large data migration from multiple legacy systems. I found something made by KingswaySoft which seems to include packages and connectors for NetSuite. Looks promising but I’m looking for others who have had success.

Hi Kevin, others may chime in but personally this is the first time I heard about SSIS so nothing to comment on "having had the success". If you're looking for an enterprise-level middleware for NetSuite and expect a higher chance of success in implementation, Boomi is the most popular choice.
