Source to target

The source to target model is an upgrade option available for upgrading to Dynamics AX 2012 from the previous major versions (From AX 4.0 or AX 2009). In this model, the final data upgrade activity will move the entire database (all data, transactions, and companies) into Microsoft Dynamics AX 2012 R3. In order to minimize the downtime window of the upgrade, Dynamics AX 2012 provides the ability to preprocess the data in the source system. The following diagram shows the source to target upgrade model:

In-place upgrade

An in-place upgrade model is applicable when upgrading to Dynamics AX 2012 R3 from the previous Dynamics AX 2012 versions. In this model, the upgrade is performed directly on the target system.
