CCS/CCSTUDIO: Import CCS3.1 project into CCS7

The format of CCS 3.1 projects is similar to that of CCSv3.3 so you can use the menu item "Project->Import Legacy CCSv3.3 Projects" to import them into CCSv7. Take a look at this page - it was written for CCSv4 but many of the suggestions should apply to CCSv7:

However, depending on the complexity of the project the migration that happens during import may not be completely clean (especially due to jump across several CCS versions), and may require some manual post-migration updates. In some situations, it may be more efficient to create a new project in CCSv7 and copy over all the source files and build settings from the 3.1 project, rather than work out issues that come up after migration. To do that it helps to have an understanding of the difference in project file formats between CCS3.1 and CCSv7.

Also if your 3.1 project uses DSP/BIOS, there are some additional considerations. Please check this thread:

Hope this helps!

Thank you.

I nedded to manually adjust the project but the "Project->Import Legacy CCSv3.3 Projects" helped me going through it.
