This seems to be related to the Data Provisioning Service Resource ID. When I provisioned DPS via the azure cli several months ago before the azure provider offered support, the Resource ID has the form "/subscriptions/00000000-0000-0000-0000-000000000000/resourceGroups/Prod.iot/providers/Microsoft.Devices/ProvisioningServices/prod-iot-dps". Services created now have the form, /subscriptions/00000000-0000-0000-0000-000000000000/resourceGroups/Prod.iot/providers/Microsoft.Devices/provisioningServices/prod-iot-dps". When I manually import (edit) the state and use "ProvisioningServices" a terraform plan crashes. When I use "provisioningServices" the plan succeeds but believes it must replace the resource.

And I upgraded to 2.0 and it behaves exactly the same.

This has been released in version 2.7.0 of the provider. Please see the Terraform documentation on provider versioning or reach out if you need any assistance upgrading. As an example:

provider "azurerm" {
    version = "~> 2.7.0"
}
# ... other configuration ...
