Data and Code upgrade from AX 2012 R2 (CU7) to AX 2012 R3 (CU12)


Greetings of the day :)

How to do data and code upgrade from AX 2012 R2 (CU7) to AX 2012 R3 (CU12)?

Can anyone kindly suggest me, how to do the data and code upgrade? And which is the best way to achieve this? And provide me any related links.

Thanks in advance.

  • Cumulative Update 12 Installation Guide is an obvious starting point.

    Note that you can use a search engine to find such links by yourself.

    Thank you for your reply. I believe more than one approach is there for upgrade. If you suggest me the batter approach it would be great and very useful to me.

    Well, there surely are different approaches. For example, some teams don't bother to read the documentation and do something else, only to find out that their upgrade project is failing. Maybe following the process isn't such a bad idea.
    What problem are you trying to solve when you something better? What do you consider wrong in Microsoft's process?
