Emphasizes capturing a pre-migration performance baseline (p95 response time, throughput, error rate, queue depth) and maintaining the old environment for at least 72 hours post-cutover to catch silent failures like nightly batch jobs or cron tasks that only run once a day. ## Full article daily.dev links to this article rather than hosting it.

After migrating to Render, verify 11 areas: the app boots and serves real traffic (not just a /ping health check), all environment variables and secrets resolve at runtime, the correct database is connected and all migrations have run, background worker services are deployed separately and processing jobs, cron jobs have corresponding Render cron services with proper exit codes, outbound integrations work and egress IPs haven't broken allowlists, error rates and p95 response times match your pre-migration baseline, logs flow to external pipelines, and uptime alerts are configured. _Developers navigating Render migrations track post-cutover regressions faster on daily.dev._ ### On Render, do background workers run automatically when I deploy my web service? No. On Render, workers are separate services from the web service. Deploying your web service does not start any worker processes. Each worker must be explicitly deployed as its own Render service. After deploying, you should confirm all worker services are running, enqueue a test job, verify it completes, and monitor queue depth during the first few hours — a steadily rising queue depth means the worker is falling behind. _Engineers running job queues on Render find operational gotchas like this covered on daily.dev._ ## Community discussion Top comments from developers on daily.dev. **@trevorsuna** · 0 upvotes > Keeping the old environment available for 72 hours is sensible because scheduled jobs and quiet integrations often fail outside the cutover window. I would also compare queue age and retry counts, not just queue depth, to catch workers that are running but unhealthy. ## Similar posts on daily.dev - [Ship with Confidence: Rails Production Checklist](https://daily.dev/posts/ship-with-confidence-rails-production-checklist-j9taquhqs) · Ruby Flow · 0 upvotes · 0 comments - [From Heroku to Render](https://daily.dev/posts/from-heroku-to-render-7gg0qgz7h) · RUBYLAND · 14 upvotes · 0 comments - [How to migrate feature flags without breaking production](https://daily.dev/posts/how-to-migrate-feature-flags-without-breaking-production-c8o0wfozv) · Datadog · 1 upvotes · 0 comments --- Tags: [#infrastructure](https://daily.dev/tags/infrastructure), [#cicd](https://daily.dev/tags/cicd), [#monitoring](https://daily.dev/tags/monitoring) [View this post on daily.dev](https://daily.dev/posts/your-render-migration-checklist-how-to-verify-everything-is-working-z0bxigbsn)
