Convert DB from Version 1.x to Version 2.x

[ille6]

Hi,

how can I convert my old Valentin 1.x DB into the new Version 2.0?
In the wiki docu is mentioned a method called "Valentina.Convert_1_2()", 
but I can't find such method in the current Version 4.3.

I use the .net-Version of Valentina.

Thanks for your help.
Carsten
