   | Resource using Basic SKU public IP addresses | Decision path |

   | Virtual Machine | Use scripts or manually detach and upgrade public IPs. For standalone virtual machines, you can use the [upgrade script](public-ip-upgrade-vm.md) or for virtual machines in an availability set use [this script](public-ip-upgrade-availability-set.md). |
   | Virtual Machine Scale Sets | [Replace basic SKU instance public IP addresses](/azure/virtual-machine-scale-sets/virtual-machine-scale-sets-networking#public-ipv4-per-virtual-machine) with new standard SKU. |
   | Load Balancer (Basic SKU) | New Load Balancer SKU required. Use the upgrade script [Upgrade Basic Load Balancer to Standard SKU](../../load-balancer/upgrade-basic-standard-with-powershell.md) to upgrade to Standard Load Balancer. |

-> If you have a virtual machine scale set (uniform model) with public IP configurations per instance, note these are not Public IP resources and as such cannot be upgraded; a new public IP address is required.

 ## FAQ
 
 ### Will the Basic SKU public IP retirement impact Cloud Services Extended Support (CSES) deployments?
-No, this retirement will not impact your existing or new deployments on CSES. This means that you can still create (via non-Azure Portal methods; for example, Azure CLI, Powershell, etc) and use Basic SKU public IPs for CSES deployments. However, we advise using Standard SKU on ARM native resources that don't depend on CSES when possible, because Standard has more advantages than Basic.
