Convert mxnet model (json) and param files

I have a model trained with mxnet 1.2.1 (.params and .json). Is there a way to convert it to 1.0.0 format? I would need this to run the openvino optimizer which is incompatible with 1.2.1.

Can you detail how you saved the model ?

Are you free to provide the .json and .params files? I could try myself.
