Why are my data plane proxies on a different version after an update?

[michaelschem]

Bug Description

% istioctl version
client version: 1.15.0
control plane version: 1.15.1
data plane version: 1.12.1 (14 proxies), 1.15.1 (20 proxies)

I just did an update, but my data plane version is still on 1.12.1. How can I update that?

Version

mschem@mbp cms % istioctl version
client version: 1.15.0
control plane version: 1.15.1
data plane version: 1.15.1 (32 proxies)
mschem@mbp cms % kubectl version --short
Flag --short has been deprecated, and will be removed in the future. The --short output will become the default.
Client Version: v1.25.1
Kustomize Version: v4.5.7
Server Version: v1.23.5
WARNING: version difference between client (1.25) and server (1.23) exceeds the supported minor version skew of +/-1

https://istio.io/latest/docs/setup/upgrade/in-place/#upgrade-steps if you are doing an in-place upgrade has number 6

After istioctl completes the upgrade, you must manually update the Istio data plane by restarting any pods with Istio sidecars
