Moving Scheduled Jobs Off Old Servers: Task Scheduler, SQL Agent and Cron to EventBridge Scheduler

Old servers survive because something on them runs at 2 a.m. Finding every Windows Task Scheduler job, SQL Server Agent job and crontab entry, and moving them to EventBridge Scheduler with Lambda, ECS tasks or Step Functions, with retries, alerts and an audit trail they never had.

When a decommissioning project stalls, the reason is often a scheduled job: an export to a bank, a nightly sync, a report emailed at 6 a.m. These jobs run on the server nobody wants to touch, under an account nobody remembers, and fail silently when they fail.

Want a second opinion on this for your system?

Book a free 30-minute call. You'll leave knowing what we'd do first and roughly what it costs, whether or not you hire us.

Find them all

  • Windows: export Task Scheduler tasks from every server, including the account each runs as.

  • SQL Server: list SQL Server Agent jobs and their steps; many call SSIS packages, scripts or other servers.

  • Linux: every user's crontab plus /etc/cron.* and systemd timers.

  • Record what each job does, what it touches and who notices if it stops.

Where they go

Job

Run it with

Short script or API call

EventBridge Scheduler invoking Lambda

Long-running or container-based batch

EventBridge Scheduler running an ECS task

Several dependent steps

EventBridge Scheduler starting a Step Functions workflow

T-SQL maintenance inside the database

SQL Server Agent on RDS for SQL Server, which supports it

EventBridge Scheduler handles one-time and recurring schedules in any time zone, with retries and dead-letter queues, and can call hundreds of AWS service APIs directly. The first 14 million invocations a month are free and it costs $1.00 per million after that, so nightly jobs cost effectively nothing.
