Three steps to migrate
Honest: migration takes some manual work — no "1-click magic". But it is three clear steps.
-
Export your monitors from Oh Dear
Most providers offer a CSV export of your monitor list (URL, name, interval). Save it locally — you will upload it in step 2.

Import the CSV into Enterno.io
Open /monitors → "Import" and upload the file. Enterno maps URL + interval automatically; you can adjust intervals to match your plan floor.
Open import → -
Cut over webhooks and DNS subscriptions
Point your alerting endpoints (Slack/Telegram/PagerDuty) at the new Enterno webhooks, then disable monitors on Oh Dear. Run both in parallel for ~24h to be safe.
