How to Review Terraform Changes That Replace a Production Load Balancer

11/10/2026

A Terraform plan may replace a load balancer after a naming, provider, or immutable setting change. Replacement can alter public addresses, health checks, certificates, or routing for multiple services.

What to check

Inspect replacement markers, listeners, target groups, DNS dependencies, security groups, certificates, and provider behavior. Confirm whether the address is static and identify every service attached to the existing load balancer.

Recommended next step

Plan a parallel resource and controlled traffic migration if replacement is required. Validate health checks, certificates, access logs, and rollback behavior before removing the current entry point.
