From SysML v1 to SysML v2

SysML v2 is not v1.8. This guide gives systems engineers a transferable mental model (not a mechanical element mapping) for making the transition with confidence.

• The definition/usage principle: the one concept behind the entire SysML v2 language
• Covers the 5 core element groups every v2 model starts with: Ports, Relationships, Connectors, n-ary Connections
• Explains what v1 constructs like FlowPort and ProxyPort map to in v2, and what they don't
• Practical migration guidance: when to move, when to stay on v1, and how to handle coexistence
