Dears,
I need your expertise to sort this out. I got this reply from my consultant regarding the upgradability form AX 2012 R2 to 2012 R3.
The Customized portion of the application can’t be applied on Dynamics AX 2012 R3 because the database schema is changed too seriously. It seems a different new one rather than updated version at the point of database especially. Thus, any functions of current Application can’t be tested on the new Software Package. It means that the upgrade test pass ratio is 0%.
I have searched around and I believe that their claim is wrong but I need you expert opinion about the upgradeability. Did the database change was major between R2 and R3.
Thank you so much for your support.
