System architecture diagram and item mapping (System Architecture Migration utility)
This topic describes how the System Architecture Diagrams and their items are migrated to Composite Structure Diagrams and their items.
Standard Properties migrated for System Architecture Diagram and Item Mapping
For the System Architecture Diagram and all migrated item types, the following standard properties are always migrated:
• Name
• Visibility
• Text tab properties (creates for migrated type if required)
• Applied Stereotypes and Tag Definitions (redefines Stereotypes if required)
• Tagged Values
If System Architecture Diagram items are used as model object references in rich text, those model object references are recoded to reference the migrated items.
If System Architecture Diagram items are referenced by symbols on Activity Diagrams or General Graphic Diagrams, those symbols are recoded to reference the migrated items.
 |
The System Architecture Migration Utility cannot change published Tag Definitions. If you have Tag Definitions that reference System Architecture Diagram items, those references will be lost.

System architecture diagram
A System Architecture Diagram maps to a Composite Structure Diagram.
In addition to the standard properties mentioned above, no other properties are migrated.
Actor
Actor migration is not required. Actor symbols are added to Composite Structure Diagrams as required.
Board
A Board maps to a Part (Role) that is stereotyped by the «board»stereotype. The Part is scoped to the Class that is created for the Board’s parent item (the Model or Package that owns the diagram, or a Subsystem).
In addition to the standard properties mentioned above, the following properties are migrated:
