Good day house....

please I need a best method to upgrade from nav 2009 to 2015 or 2016… moreover have tried using transformation tools and its not working fine because there are so many custom tables, forms and so on…please help me out

AND you posted the same question a third time?

yes…it because I have a lot of custom forms and the method is slowing me down…am trying to transform a large database of a company so am thinking if there is other way I can upgrade without using transformation process
