#Download Core Package

Before installation, you need to download the Core Package.

Log in to the Customer Portal to download the Core Package.

Packages are available for x86, ARM, and hybrid architectures. The hybrid package includes images for both x86 and ARM, resulting in a larger package size. Select the package that best matches your environment.

If you do not have a registered account, please contact technical support.

#Migrating from Single-Architecture to Hybrid

If you initially installed with an x86 or ARM Core Package but later need to support another architecture, you must re-download the hybrid Core Package and perform the following steps:

1. Upload the newly downloaded hybrid Core Package to any control plane node of the global cluster.

2. Extract the package and use the included upgrade.sh script to synchronize the multi-architecture images to your image registry:

   bash upgrade.sh --only-sync-image=true

3. After the script completes, check the cluster.platform.tkestack.io resource to verify whether the label cpaas.io/node-arch-constraint exists. If it does, you must remove it:

   kubectl get cluster.platform.tkestack.io global -oyaml | grep cpaas.io/node-arch-constraint
   # If there is output, edit the resource to remove the label; otherwise, you can skip this step.
   kubectl edit cluster.platform.tkestack.io global   ### Edit the labels field and delete cpaas.io/node-arch-constraint
