need to upgrade the load balancer from Basic SKU to Standard SKU in azure portal kindly share me the steps to do it

Hello @Hendry Richard,

Welcome to Microsoft Q&A Platform. Thank you for reaching out & hope you are doing well.

I understand your question about upgrading your Load Balancer from Basic SKU to Standard SKU. Azure does not allow an in-place upgrade for Load Balancers, so you will need to create a new Standard SKU Load Balancer and migrate your configuration to it.

Important Points to Consider Before Getting Started,

1. Basic and Standard SKUs cannot be used together on the same IP or backend pool.
2. Any Public IPs linked must be Standard SKU.
3. Standard SKU Load Balancer is secure by default, so make sure the necessary NSG rules are configured.
4. Schedule a maintenance window, as there may be a brief connectivity interruption during migration.

Manual Migration via Azure Portal:

1. Document the current setup, including frontend IPs, backend pools, rules, and probes.
2. Create a new Standard SKU Load Balancer within the same region and VNet.
3. Recreate the configuration:

·       Add frontend IPs using Standard SKU and static Public IP.

·       Set up backend pools, probes, and rules again.

1. Update NSG rules to permit necessary traffic.
2. Point NICs or VMSS instances to the new backend pool.
3. Check that traffic flows correctly, then remove the Basic Load Balancer.

You can upgrade from a Basic to a Standard Load Balancer by using the link below:

Via PowerShell:

Use the official PowerShell migration module AzureBasicLoadBalancerUpgrade. This tool will:

1. Back up your Basic Load Balancer configuration.
2. Create a new Standard Load Balancer with similar settings.
3. Migrate backend pools, health probes, and NAT rules.
4. Update the associated Public IPs to the Standard SKU.

Note: For AKS or VM Scale Sets, refer to the migration guidance designed for AKS. Ensure that outbound connectivity is configured for the Standard SKU, using either outbound rules or a NAT Gateway.
