[NOTE]

|
====
|
|
If your control plane is not currently multi-architecture enabled, the upgrade process will first migrate the cluster to a multi-architecture image and then apply the version upgrade. Multi-architecture clusters are capable of running both x86-based and Arm-based workloads. Clusters created after 25 July, 2024 are multi-architecture enabled by default.
