Help Needed with upload of Succession Data Model in SF!!!

Dear All,

I was trying to do the 1^st chapter of EC in learning hub. In the first exercise, it mentioned to upload the succession data model. I had downloaded the latest data model (1608) provided as part of the learning hub course. Name of the data model is 1608-data-model

I am using instance SFPART005459 and I downloaded the succession data model from the instance and stored it in a folder as a back-up. Name of the data model is SFPART005459-data-model.

I renamed the data model downloaded from learning hub from 1608-data-model to SFPART005459-data-model and tried to upload it in provisioning. When I try to upload it, it simply hangs at the below stage.

Can anyone help me with this? Am I doing something wrong here? I was just trying to use the latest data model for the practice exercise. Below is the screenshot which I get.

Any help will be highly appreciated.

Thanks and regards,

Vivek Barnwal
