i have a backup file from Navision 3.56 Dos (*.#bk). Only the company-data are included. I have read that I could restore the backup in a new Database with client 4.00, but i get after a short time an error - Internal error 10005 in Modul 19. Have anyone a idea for this problem. Is this even a possible way to restore Data form 3.56 in a new Database 4.00, or ist there an other way to migrate the Data. Thanks for your help.
