Hello @louis-philippe redaud , Thanks for using Microsoft Q&A Platform.
Generally, you can use the Copy Model
API to copy your custom model to a different region or a different subscription when you provide the target location and subscription details in the copy authorization request. To learn more about this please refer to this documentation here : https://learn.microsoft.com/en-us/azure/ai-services/document-intelligence/disaster-recovery?view=doc-intel-3.1.0#copy-api-overview
Coming to your question, as we know the Document intelligence studio tool stores labels and document files in your blob storage account containers. So, you can directly create a new project under your resource by linking to this storage container which contains all your training data including labels.file. Once project is created you can see also your training data in the current project.
These are the best possible ways you can try. Similar question has been addressed here you can refer to this.
I hope this helps.

Vasavi
