Met dank aan Kevin Kidder die me attendeerde op het volgende artikel op TechNet  over een inplace upgrade van Dynamics AX 2012 naar R2.

published on TechNet about the upgrade from AX 2012 to AX 2012 R2 – a listing of the steps involved can be found a little way down in the page http://technet.microsoft.com/en-us/library/jj733502.aspx in the section Upgrade from Microsoft Dynamics AX 2012 or AX 2012 Feature Pack to AX 2012 R2 – you can collapse the first section about upgrading from non-retail to retail to find it easier.

Enjoy
