Understand what is not migrated from PI MDB to PI AF

In PI MDB, the following objects are not migrated to or synchronized with PI AF:

• OSI proprietary Modules:

  The modules %OSI, %OSI_MCN, and %OSI_ManagedPI store metadata for PI applications. These modules are not migrated to PI AF. This metadata remains available to PI MDB applications; PI AF applications do not need it and cannot access it.

• PI Heading Sets, PI Headings:

  PI Heading Sets and PI Headings are not migrated to PI AF. PI AF elements are not assigned a PI Heading even if the corresponding PI module references a PI Heading. PI MDB clients still display the PI Heading associated with a PI module but PI AF clients cannot display PI Headings.

• Batch Data and Batch Subsystem (BSS) Units:

  After the migration, you can continue to access batch data on the Data Archive server. See Learn how batch objects are migrated for more information.

In PI AF, all objects under a Data Archive element are synchronized with PI MDB on the corresponding Data Archive server. Any content that is not under a Data Archive element is not synchronized with PI MDB.
