Explanation
Step 1: Notify all the users in the int1 region and schedule a maintenance window.
Step 2: Select the subscription that was used to perform the initial registration.
Note: You need to change the int1 region to use the capacity model.
Change the billing model and registration name of the int1 region.
The int1 region runs a high number of Windows virtual machines that use pay-as-you-use images.
Change billing model, how features are offered, or re-register your instance This section applies if you want to change the billing model, how features are offered, or you want to re-register your instance. For all of these cases, you call the registration function to set the new values. You don't need to first remove the current registration.
# select the subscription used during the registration
Select-AzSubscription -Subscription '<Registration subscription ID from portal>'
# rerun registration with new BillingModel (or same billing model in case of re-registration) but using other parameters values from portal Set-AzsRegistration -PrivilegedEndpointCredential $YourCloudAdminCredential -PrivilegedEndpoint
$YourPrivilegedEndpoint -BillingModel '<New billing model>' -RegistrationName '<Registration name from portal>' -ResourceGroupName '<Registration resource group from portal>' Step 3: Run the Set-AzsRegistration cmdlet.
You can use Set-AzsRegistration to register Azure Stack Hub with Azure and enable or disable the offer of items in the marketplace and usage reporting.
To run the cmdlet, you need:
A global Azure subscription of any type.
To be signed in to Azure PowerShell with an account that's an owner or contributor to that subscription.
