Hi All,
I am currently working on both code and data upgrade from AX 4.0 SP2 to AX 2012 R3 Cu12 and i am getting the following error after specifying the Server and database name in the target "connect to source database" checklist.
Please let me know, how i could fix this issue.

Thanks for your input, i will perform the above actions and let you know.
Take a backup of your in progress data and model databases just in case something would go wrong.
Export your models from all customized layers in the partially upgraded environment.
Create a new Database installation using the AX 2012 installer kit, and mark all models (foundation, foundation upgrade, foundation labels). Export the modelstore using the AX Management Shell from this fresh instance.
Import the modelstore with ID overwrite over your in progress upgrade environment.
Import the models to the layers which you have saved before.
Do an AXBuild to compile the newly added elements.
Hi,
When installing AX 2012 R3 there was the option "Install foundation labels" that was unchecked by default
Since i have already installed Ax 2012 and started the upgrade checklist in ax 2012, please let me know on how to install the foundation upgrade model.
Please mark the answer as verified.

Thanks for the clarification it was my mistake, i did not choose the foundation upgrade model while installing the Ax 2012. Since installation is already done, please let me know on how to install the foundation upgrade model.
André was not referring to marking the DB for upgrade, but when you do a clean installation of an AX 2012 environment, then you may choose what models should be installed. There the Foundation, Foundation Labels and Upgrade models should all be ticked in order to have the necessary objects in the modelstore required for a code and data upgrade.
Hi Andre,
Yes, "register database for upgrade from Microsoft dynamics AX 4.0 or Microsoft Dynamics AX 2009" check box is selected during the installation process of AX 2012.
Thanks,
Wilbert
Hi Wilbertregan,
During setup, did you choose to install the upgrade models? The missing class is probably part of the additional model.
Any suggestions..? about this error
