Hi,

Some drives were changed between MQX4.1 and MQX 3.7 (GPIO driver for example); RTCS stack was extended by IPv6 protocol support; some board support packages were removed from the release; some drivers were added and some bugs were fixed. For more details, please ckeck the MQX Release Notes.

So, it is a little difficult to answer your questions, if your project is not using drivers that have been discontinued in MQX 4.1 then you only need to create a new project in MQX4.1 and copy your old code to the new project. In other case you need to change the code in order to replace all functions that implent obsolete drives.

Have a nice day!

Have a great day,
Regards
Sol
