CUSTOM DOMAIN
Migrating Off a Homegrown Domain Setup
A practical clinic for platform teams ready to retire brittle DNS and certificate code they built in house.
You built the custom domain feature yourself, and it worked well enough to ship. Then came the wildcard certificate renewals at odd hours, the DNS edge cases across dozens of providers, the verification flow that fails silently, and the support tickets you cannot reproduce. If you are a platform or infrastructure engineer carrying that code, this clinic is about a calmer path forward. We will walk through migrating your customers off a homegrown setup and onto a fully managed service, without breaking the domains that are already live.
What you will learn
- How to inventory your current custom domain paths, including DNS records, ownership checks, and certificate issuance, so nothing is missed in the move.
- How a control plane and an edge that terminates TLS and routes traffic replace the pieces you now maintain by hand.
- How customers connect through one click provider authorization, a provider API token, or a guided manual flow that verifies automatically across 63 DNS and registrar providers.
- How on demand certificate issuance and renewal remove the cron jobs and expiry alarms from your rotation for good.
- How strict multi tenant isolation keeps one customer domain from ever affecting another.
Who this is for
Platform and infrastructure engineers who own the custom domain experience at a SaaS company and want to hand off the operational weight while keeping full confidence in what their customers see.
What we will cover
- Mapping a homegrown domain setup and naming the parts that cost you the most time.
- Designing a migration plan that moves live domains safely and in stages.
- Connecting customer domains that go live in about 30 seconds through the three onboarding paths.
- Handing off certificate issuance, renewal, and edge routing to a managed control plane.
- Cutting over, validating, and decommissioning the old code with confidence.
This is a live 60 minute session with time for your questions at the end, so bring the parts of your setup that worry you most. Everyone who registers receives the recording afterward.
