Azure Stack HCI 23h2 upgrade & Azure local Resource
Good evening,
After upgrading from 22H2 to 23H2, we encountered an issue where the Azure Local resource in the Azure portal appears as "not connected recently." Additionally, we are not seeing the "Your cluster can be upgraded to the latest version" option, likely due to this connection issue.
Despite successful connectivity tests and extensive troubleshooting, the resource remains unsynchronised with Azure. As a result, we tried deleting the Azure Local resource and re-registering the nodes.
Now, while both nodes are successfully registered and connected to Azure and passing the Invoke-AzStackHciUpgradeValidation , we are unable to find a way to re-register the Azure Local resource to proceed with the "Install the solution upgrade via Azure portal" step.
The only option I see is going through the "Deploy Azure Local" process in Azure Arc. However, I believe this would overwrite existing settings and VMs, causing significant disruption—especially since this is a production cluster upgraded from 22H2.
Is there a way to re-register the cluster and restore the Azure Local resource using existing settings, so we can proceed with deploying the rest of the solution upgrade via the Azure portal?
Any guidance would be greatly appreciated

Just an FYI. Microsoft was taking a phased approach when making the upgrade to 23H2 available to clients in the Azure Portal. We had a test 22H2 Cluster that we performed all of the steps late last year and also did not see the banner in the Azure Portal so could not complete the final step. We had a few discussions with various Microsoft engineers and our Account Manager, and they finally made it available to us recently. So the banner appeared in the Portal and we able to complete the upgrade to 23H2.
Any chance to fix by Re-register by using PowerShell?
Unregister-AzStackHCI -Name "YourClusterName" Register-AzStackHCI -Name "YourClusterName" -Location "YourAzureRegion" -ResourceGroupName "YourResourceGroup" -SubscriptionId "YourSubscriptionId"
