I am using VMSS with basic tier load balancer and public IP address. When I am doing application update, I want to create new VMSS to make sure it is not affecting the old VMSS. Now I am creating new VMSS with new IP and load balancer. However, I do not want the IP to change. Is there any way to create a new VMSS connecting to an existing basic tier load balancer?

You cannot add multiple Azure VMSS to one Basic tier Azure load balancer. Azure Basic load balancer only supports virtual machines in a single availability set or virtual machine scale set (this is a single VMSS). Reference : https://docs.microsoft.com/en-us/azure/load-balancer/skus
However, Standard load balancer supports any virtual machines or virtual machine scale sets (multiple) in a single virtual network. So, you can easily configure a VMSS with an existing Standard SKU load balancer using the Azure portal: https://docs.microsoft.com/en-us/azure/load-balancer/configure-vm-scale-set-portal
