How to fix failed basic ip "provisioningState": "Failed"

To fix the failed provisioning state of the basic public IP associated with your Virtual Network Gateway migration, you should first ensure that all resources involved in the migration are in a succeeded state. If any resources are in a failed state, the migration cannot proceed successfully.

Here are the steps you can take:

1. Check Resource States: Verify that all related resources, such as the Virtual Network Gateway, connections, and public IPs, are in a succeeded state. If any are in a failed state, you will need to address those issues first.
2. Restore the Provisioning State: You can restore the succeeded provisioning state by running a write (PUT) operation on the resource. This can be done using Azure PowerShell. For example, you can use the following command:

      Get-AzPublicIpAddress -Name "your_resource_name" -ResourceGroupName "your_resource_group_name" | Set-AzPublicIpAddress
   

   Make sure to replace your_resource_name and your_resource_group_name with the actual names of your resources.
3. Retry the Migration: Once all resources are in a succeeded state, you can attempt the migration process again.

If you continue to face issues, consider checking the Azure documentation for further troubleshooting steps or submitting a support request to Azure support.
