Ads migration doesent migrate categories

My 6.16 dolphin ads have totall different categories, and subcategories

How does the migration script solve that problem?

Can you submit a ticket, to make the migration script migrate categories and subcategories as well?

Does anyone else have this problem? Where you changed categories and subcategories in Dolphin 6, then after it migrates to dolphin 7, it shows as if you have 1 ad, when in fact you have hundreds..

Please let me know if your ads migration went smoothly, even though you haad custom categories in old dolphin..
