What’s new in AX 2012 Data upgrade??
In earlier version, all upgrade tasks were performed on a single production system and during that time, the system was offline for regular users
In AX 2012, the business data is pre-processed on to a source system which is the system that runs Microsoft Dynamics AX 2009, while that system is live.
While data on the source system is pre-processed, A separate, offline target system can be built, which is the system that runs Microsoft Dynamics AX 2012.
So the above upgrade model is known as Source-to-Target upgrade model.
When pre-processing on the source system is completed, and the target system is ready, you enter single-user mode on the source system. You then bulk copy your data into the target system, run post-synchronization upgrade scripts, and perform testing. At this point, the target system can go live.
