OPTION 1:
You can use the ExportProject and ImportProject APIs to migrate your iteration from one custom vision resource to another. Note: when importing, you may have to url-encode the token.
OPTION 2:
The following document shows how to migrate custom vision projects from one region to another. Download the sample script contained in the document and run the following commands to migrate your project from one subscription or region to another. However, you'd need to re-train the model. Thanks.
pip install -r requirements.txt
#same region
python migrate_project.py -p "<project id>" -s "<source training key>" -d "<destination training key>"
#different regions
python migrate_project.py -p "<project id>" -s "<source training key>" -se "https://region.api.cognitive.microsoft.com" -d "<destination training key>" -de "https://region.api.cognitive.microsoft.com"
