EKS and statefulset

Hello,

I have an EKS cluster and I'd like to upgrade this cluster with bigger nodes. So I have created a new node group with the desired size four these new nodes, and I'm migrating all apps on them (cordon an old node, drain it to force deployments to recreate pods on new nodes).

I have a problem with some statefulset app. The pods areforced to use the same node, so when I want to migrate to the new nodes, the pods are stacked in pending because the pvc (gp2) used is also b ind to the same node.

How shoud I do to migrate all statefulset app from all nodes to new one without loose all data ?

Thanks.
