Reply To: Upgrade from AX 2012 R2 CU7 to AX 2012 R3 CU12

Hello Saurabh,

I don’t see anything wrong with your planning. You can also swap step 2 and 3, so that first import database on TEST and then upgrade SQL. I haven’t seen any issue for minor upgrade of SQL (sp2 to SP3). But I would add that as you are currently on R2-CU7, you need to take care of few things such as DIXF, you need to remove that from installation as DIXF is available in standard R3 installations.

Also I have seen DIXF service to crash with few versions of SQL. I can remember SQL server 2012 SP2. You need to watch how your SQL version will be at supporting DIXF service. Test it well.
