@Md Asfaque With form recognizer there is a functionality 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. The details about this feature is available here in the documentation.
If you would like to follow an example to run these steps or API you can refer this thread for more details. After copying your model to the required subscription/region a new target model id will be provided which can be used in your new account or application with the same results as the original model. Thanks!!
