### Will the module migrate my frontend IP address to the new Standard Load Balancer?

Yes, for both public and internal load balancers, the module ensures that front end IP addresses are maintained. For public IPs, the IP is converted to a static IP prior to migration (if necessary). For internal front ends, the module attempts to reassign the same IP address freed up when the Basic Load Balancer was deleted; if the private IP isn't available the script will fail (see [What happens if my upgrade fails mid-migration?](#what-happens-if-my-upgrade-fails-mid-migration)).

In case there's no network security group associated with the Virtual Machine Scale Set, a new network security group will be created to preserve the same functionality. This new network security group will be associated to the Virtual Machine Scale Set backend pool member network interfaces. It will allow the same load balancing rules ports and protocols and preserve the outbound connectivity.

1. [Remove the new Standard Load Balancer](./update-load-balancer-with-vm-scale-set.md) (if created). Depending on which stage of the migration failed, you may have to remove the Standard Load Balancer reference from the Virtual Machine Scale Set network interfaces (IP configurations) and Health Probes in order to remove the Standard Load Balancer.
