Standard_D8s_v3 - Cascade Lake CPU architecture preferred

Question

My AKS node pool is configured to use Standard_D8s_v3 node size. These nodes can be any one of four CPU architectures (Cascade Lake, Skylake, Broadwell or Haswell).

My workloads are failing on all architectures, except Cascade lake. However, I can not vertically scale to v4, which uses only Cascade Lake.

Hence my question is, is there a way to get my nodes to only be Cascade Lake nodes?

once the node pool is created you will not be able to scale to a different SKU you can only increase or decrease the node count. to switch to new SKU you may need to add a new node pool with V4 series and drain the workloads to the new node pool and delete the existing one.
