Hi.
There must be a bug in Migrator::loadCountListContinue, at least when called from portProducts, which prevents the import of all products.
We are migrating a shop with ~2400 products, and over the amount ~150 products were not imported, despite the import log showing it elaborated the full number.
we checked the query and is fine, so the problem must reside in that call.
We're sorry but cannot investigate further, we already lost 5h time with our customer...
sorry to hear that, we migrated often more than 2k products, so I wonder that you had the problem. Common is that the migrator makes 1000 products in one load and you have to repeat it.
