    We have a Basic load balancer that was deployed as part of Azure Active Directory Domain Services (AADDS). Do we need to upgrade this manually, or do we even need to upgrade this?

    On the AADDS page (https://learn.microsoft.com/en-us/azure/active-directory-domain-services/network-considerations), it warns:
    "Don't delete or modify any of the network resource created by Azure AD DS, such as manually configuring the load balancer or rules. If you delete or modify any of the network resources, an Azure AD DS service outage may occur."

    Hi,

    Currently, in LCS deploying a tier 1 environment creates a basic sku load balancer.

    What will be happening to existing ones deployed via LCS? Can they be upgraded as well?

    Will LCS in future be updated to deploy standard load balancers and if so what are the dates?

    Thanks,

    barry

    After migrating a load balancer to Standard SKU using the provided power shell script, we ran into issues with internet connectivity of our VMs behind that load balancer. There is no real good documentation about this available, so I filed a bug on the Github space for the LB Migration documentation -> https://github.com/MicrosoftDocs/azure-docs/issues/120250 As it turned out, the internet routing has to be recreated manually after using the PowerShell migration script, by deploying a NAT gateway or assigning public IP addresses either. Depending on the resources connected to the VNet subnet, using a NAT gateway might be impossible.
