Upgrade toolkit localization

pedroccda

I'm upgrading form 3.70 to 4.00. I have seen that in IT Upgrade Toolkit there are different fob:

THE LOCALIZED OBJECT FOB

Local\Objects\IT_Nav400_UPGTK370_1.fob
Local\Objects\IT_Nav400_UPGTK370_2.fob

and OTHER OBJECT FOB

Upgtk\Data Conversion Tools\370\Upgrade370400.1.fob
Upgtk\Data Conversion Tools\370\Upgrade370400.2.fob

I'm asking myself why 4? :-s They would be only 2... I think I have to use only the Local\Objects\... but the manual is not clear about it.
:-k

Someone has tryied it yet? Any idea?
