So, just want to get clarified whether upgrading from such low version means just referencing latest dll's & implementing new features or any other extra care has to be taken in terms of architectural changes in the design..?
Yes, in some cases there are some possibilities for API names in v3.302 to be renamed or removed in latest essential studio version based on changing requirement. Those cases needs to analyzed and modified.
Syncfusion Windows Form “Diagram” has a major API and Architectural changes in the version V5.1. I have attached the migration document which will help you to migrate from v 3.3 to V5.1.
Here is the Migration Document:
Upgrading from the lowest version (3.2) to latest version (12.3) need some API changes to the existing code. There will be some changes in default property settings and behaviour.
Most of these changes will be based only on diagram API, but it does not depends upon other application’s architecture or design.
