X-Cart Database To 2.x

[COLOR=“Purple”]I am running the 1.3.5 sp4 on one site, but want to go for the most recent CS version on my larger site that is presently running on X-Cart. The problem is converting the database. CS-Cart insists all one needs to do is convert the DB into a CSV file, and it can “easily” be imported into the 2.x CS-Cart.

The two do not seem to mesh at all. Are there any secrets we should know about ? Has anyone scaled these complications & made it work ?
