Article #28827: C++Builder project version compatibility
Question:
Are C++Builder5 projects compatible with C++Builder6? How about backwards
compatibility, i.e. C++Builder6 projects compatible with C++Builder5?
Answer:
For the most part, yes if you have developed a project in C++Builder5, when
you upgrade to C++Builder6 you should be able to easily open your
C++Builder5-created project in C++Builder6, and vise-versa. If you run into
problems with this issue, we suggest that you contact Borland Developer
Support.
