Azure Basic Load Balancer retirement

Ramona Istrate 85

Hello,

I have the following scenario in Azure: we have two Exchange servers hosted in Azure that are members of two Basic Load Balancers—one internal with a private IP, and one external with a public IP.

Based on documentation, when using multiple load balancers for the same backend pool members, it's recommended to migrate to Standard Load Balancers simultaneously using a PowerShell script.

However, I came across a step in the documentation that isn't entirely clear: "Configure outbound traffic for Load Balancer." Since the virtual machines are already part of both an internal and an external Load Balancer, my question is—do I still need to configure outbound traffic in this case?

Another question: the external Load Balancer is associated with a Basic Public IP. Will this Basic Public IP be automatically migrated as part of the script?

Thank you

Hi @Ramona Istrate

Thank you for reaching out on Microsoft Q&A forum.

Regarding your query Configure outbound traffic for Load Balancer. Since the virtual machines are already part of both an internal and an external Load Balancer, my question is—"do I still need to configure outbound traffic in this case?"

Yes, you need to configure outbound traffic for your load balancers, being VMs are already part of both an internal and external Load balancer. As its recommended by Azure for not using the default outbound access for enhanced security and control. We should configure outbound rules to ensure proper traffic flow.You need to explicitly define outbound rules or use a NAT Gateway.

Answer to 2nd question:"the external Load Balancer is associated with a Basic Public IP. Will this Basic Public IP be automatically migrated as part of the script?"

No, Basic Public IPs cannot be automatically migrated to Standard SKU. You must create a new Standard Public IP and associate it with the Standard Load Balancer.
