Upgrade Rancher 1.6.12 to 1.6.28

Hi,

Just wondering if I upgrade my rancher server from v1.6.12 to v.1.6.28. Do I need to upgrade my lb services from rancher/lb-service-haproxy:v0.7.15 to rancher/lb-service-haproxy:v0.9.11 ?

Or will v.1.6.28 work with rancher/lb-service-haproxy:v0.7.15 ?

Regards
