The objective is to upgrade the Nav 2009 R2 Version W1 4.0 to Nav 2013 R2
However, when running the object upgrade601700.fob we are having errors. Hence think we have to upgrade Version W1 4.0 to Version W1 6.0 then to upgrade to 2013 R2.
Do you know the exact tool that must be used for the upgrade because have search the partnersource but no specific info have been gathered
