DMS replication instances should have automatic minor version upgrade enabled
Checks that automatic version upgrade is on for the DMS replication instance. With it on, DMS moves the instance off a deprecated engine version during its maintenance window, so it keeps receiving the bug fixes and security patches that newer engine versions carry.

How to fix it
- Interrupts service: When DMS applies an engine upgrade in the maintenance window, the instance shuts down while it upgrades, so replication on it stops until the upgrade finishes.
In the console
Database Migration Service → Replication instances → the instance → Modify
- Automatic version upgrade
- Enabled
- Maintenance window
- A weekly window (UTC) when replication on this instance can pause for an engine upgrade
With the AWS CLI
aws dms modify-replication-instance --replication-instance-arn <replication-instance-arn> --auto-minor-version-upgrade --region <region>With Terraform
resource "aws_dms_replication_instance" "this" {
replication_instance_id = var.replication_instance_id
replication_instance_class = var.replication_instance_class
auto_minor_version_upgrade = true
