## TL;DR

If you still run the Fluentd-based Coralogix integration on ECS, plan the migration to the OpenTelemetry collector integration now, do not wait for the legacy endpoints to go dark.

## Steps

1. If you still run the Fluentd-based Coralogix integration on ECS, plan the migration to the OpenTelemetry collector integration now, do not wait for the legacy endpoints to go dark. Migrate Fargate deployments to the OTel ECS Fargate integration and EC2 deployments to the OTel EC2 path, then verify logs arrive in the Coralogix UI before decommissioning the Fluentd sidecar.

## When to use
