Thank you Vilmos,
But i followed the below steps only
Step 1: Imported the Customer DB from AX 2012 R2 CU7
Step 2: Updated the UserInfo Table with the contoso/Administrator user.
Step 3: Delete the SYSServerSessions,SYSClientSessions records from the database backend.
Step 4: Check the Model List
Step 5: I exported the ModelStore and saved in a file location, “only for backup purposes”
Step 6: I uninstall all the component of AX 2012 R2 expect the AOS in the control panel. I also stop the AOS server.
Step 7: uninstall the components
Step 8: Installing the AX 2012 R3 Support file and configuring the DB
DB
Configure the Database
Since we have only Foundation and Foundation label in your environment, I also selected only the two model file in this environment
When I try to move next, it is asking to uninstall as below. I didn’t uninstall I just continue the setup
And installed the DB in the environment.
Additionally I installed the two components for checking the modification in the environment.
And I can see a successful output in the environment as below.
Now I am uninstalling the AOS Server (AX 2012 R2 CU7)
Installing the AX 2012 R3 AOS Component:
Step 1 : Now I started the setup for AX 2012 R3 RTM and selected only the AOS Server
I choose the default on this option and continue the setup
Now I installed the client and debugger to see the check list is updated or not.
I run the AXBuild XPPCompileAll
Step : I installed the AX 2012 R3 Client and all other needed components.
I started the client and could see “The Model store has been modified” Window.
We tried completing the code upgrade checklist.
Now you have to follow the upgrade steps according to the standard.
