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.
