The ability to migrate data from one system into another was very easy with no problems at all, even after having some issues when it came time actually migrating our files over as well! I think that their customer service could improve but they are great overall so far especially since we have not had any major challenges yet!! Nothing really comes across my mind right now just positive thoughts about this product/service :) Migrating large amounts of information between two different platforms like Salesforce & SugarCRMs which makes life easier than ever before!
