On our test environment we created custom Form Recognizer model. Is there a way to reuse this model on PROD environment? Prod environment is under different subscription.
I cannot find a way to somehow "export" model and move it to other environment. Do I need to create new model from scratch?
You can use the Copy Model API to copy a model between regions and subscriptions. See here for more details - How to Copy API - https://learn.microsoft.com/en-us/azure/cognitive-services/form-recognizer/disaster-recovery#copy-api-overview
