Upgrade Sitecore Managed Cloud Containers from AKS 1.23 to 1.24

Question

AKS will deprecate Kubernetes version 1.23 on April 2nd 2023. Customers whose Sitecore Managed cloud solution based on the older AKS cluster version(1.23 or older) will face issues maintaining their environments. After April 2nd 2023, customers running version 1.23* will not be able to:

• Scale their AKS nodes
• Manipulation of AKS and VM infrastructure

Is there any detailed documentation pertaining to the steps required to upgrade the package versions and the AKS cluster version?

Upgrade Instructions

1. Download an upgrade package for the required topology and version from the storage. There is a list of available upgrade packages:

Sitecore 10.1.0:

• mcc.xp.upgrade.10.1.0-r.0.1.287527.nupkg
• mcc.xm.upgrade.10.1.0-r.0.1.287527.nupkg
• mcc.xc.upgrade.10.1.0-r.0.1.287527.nupkg

Sitecore 10.1.1:

• mcc.xp.upgrade.10.1.1-r.0.1.287525.nupkg
• mcc.xm.upgrade.10.1.1-r.0.1.287525.nupkg

Sitecore 10.1.2:

• mcc.xp.upgrade.10.1.2-r.0.1.287524.nupkg
• mcc.xm.upgrade.10.1.2-r.0.1.287524.nupkg

Sitecore 10.2.0:

• mcc.xp.upgrade.10.2.0-r.0.1.287520.nupkg
• mcc.xm.upgrade.10.2.0-r.0.1.287520.nupkg

2. Install the upgrade package to your solution (follow the guideline for Sitecore 10.1 or Sitecore 10.2).
3. Run the Infrastructure pipeline.
4. Run the Application pipeline.
5. Run the check cluster upgrades pipeline. You will see the message to upgrade the AKS in the logs.
6. Run the cluster version upgrade pipeline (Kubernetes_version 1.24 - select the latest available patch version received from the pipeline in step 5).
7. Once the above pipelines run successfully, Go to Kubernetes service on Azure Portal and check the AKS version

Note: Upgrade your solution only if the version you have is earlier than the ones listed below in the Solution section. To find out the version of your solution, view the solution.json file in the infrastructure repository of your Sitecore Managed Cloud Containers Azure DevOps project. If your environment is still running on AKS 1.22, it is recommended first to upgrade to AKS 1.23 and then follow the above steps.
