Migration Guide for ARCHICAD 21

You can open older-version files (ARCHICAD 8.1 and up) in ARCHICAD 21.

Since ARCHICAD features are developed and improved in each succeeding version, your older-version project will, in some respects, work differently after you migrate it to ARCHICAD 21. This Migration Guide calls your attention to these changes.
