PI Units are a type of PI Module and as such they are migrated to PI AF. When AF Link migrates PI Unit Modules to PI AF, it creates a PI AF Category named PIUnit and assigns this Category to all elements that represent migrated PI Units. You can access these PIUnit Elements in PI AF, just as you access Elements representing other PI Modules.
You cannot however, access batch data in PI AF. PI Units have associated batch data that is stored in a PI Point called a PI Unit Batch storage point. This batch data is not migrated. It remains in the PI Batch Database on the Data Archive server. After the migration, all your existing batch clients based on the Module Database continue to work as usual. However, PI AF-based applications cannot access the batch data.
Note: Batch Subsystem (BSS) Units are not migrated to PI AF. If you want to migrate BSS Units, then you must first convert them to PI Units.
