Publisher documents and templates will automatically upgrade from 7.3 or later. However, due to metamodel changes (in 7.4, to Class, Signal, Interface, Datatype, State Machine, and Dependency) and profile changes (in 8.0, for example, renaming stereotypes in the SysML, and in 8.1, changes to UPDM and MARTE profiles), some manual updates to the document definition may be needed to extract the required content in 9.0.

After upgrading, any custom styles created in previous versions may be recovered from C:\ProgramData\PTC Integrity Modeler\Publisher\Stylesheets\DocumentGeneration\CustomDocBook.
