The Upgrading Track

Essential steps to modernize your legacy Delphi and C++Builder codebase, ensuring compatibility, security, and performance on the latest RAD Studio release.

Secure Your Foundation

The Upgrading Track is focused on resolving technical debt. Before you can add modern UI paradigms or mobile cross-compilation to a legacy application, the structural foundation of the code must be sound.

If your codebase is stuck on an older version of Delphi (like Delphi 7, 2007, or even early Unicode versions), attempting to compile it in the latest RAD Studio release will inevitably trigger some errors. The guides in this track break down the most common migration hurdles into manageable, logical steps.
