Extend custom trained yolo model with new classes

Hello,


I have a custom trained YOLO v8 model with 2 classes. Now I want to add 3 classes to this model, so that the model can identify 5 classes.

Is it possible to do that? I have already prepared the folder structure for the training process, but dont know how to connect the old model with the new images and labeles (im using colab for training).

​

Thank you for you answers!
