I follow the 1.2 Migrating User Application Drivers on Migration Guide.

I created a new project, imported UserApp from existing Identity Vault,
make a backup copy, then Migrate. This step migrates the local definition
of the driver found in the IDM Designer workspace. Is this IDM Designer
workspace come with IDM351 User Application version when I installed
Designer 211 ? So, during Migrate process, it'll pick up 3.5.1 User
Application from workspace migrate to the imported 3.5 User Application
(from my eDirectory), means that migrate process is finished, the imported
3.5 User Application becomes 3.5.1 version. Is my understanding correct ??
