Hello,
There is no official way to migrate toolbox from one computer to another. One solution that MIGHT work would be to go to the addons folder in MATLAB and copy-paste the entire toolbox on the new computer in the addons folder. Then, I recommend to run the mbd_s32k1_path to make sure everything is in path. Please make sure you generate a new license file for the new laptop.
Important! Before trying these, please make sure you have backup in case something fails.
Regarding the issue about EERead, EEwrite, I don't know yet. Let me investigate and I will come back with an anwser.
Best regards,
Sorin Bancila
