Auth0 → Okta Customer Identity Cloud migration playbook
Migrate from a classic Auth0 tenant to the Okta-integrated Customer Identity Cloud — same underlying product, but consolidated billing, unified admin, and the Okta platform integrations.
TL;DR
Auth0 and Okta CIC are the same product (Okta acquired Auth0 in 2021). Migration is usually less about technical work and more about commercial consolidation — moving from a classic Auth0 contract to a CIC contract under your Okta master agreement.
Auth0 (classic tenant)
Okta Customer Identity Cloud
Typical timeline
4-8 weeks (mostly commercial; technical work is often minimal)
Why teams move
- Workforce already on Okta — consolidating CIAM into the same vendor relationship
- Commercial consolidation — single MSA + invoicing + procurement
- Access to Okta platform integrations (Workflows, Conditional Access patterns) from the CIAM tenant
- Future-proofing as Auth0 product roadmap converges into the Okta platform
The migration in 3 phases.
1. Phase 1 — Commercial alignment
2-4 weeks
- Inventory current Auth0 contract terms + renewal dates
- Engage Okta CIC team for unified contract sizing
- Negotiate the swap — credit remaining Auth0 term toward CIC
2. Phase 2 — Tenant migration
1-2 weeks
- New CIC tenant provisioned (or existing Auth0 tenant relabeled)
- Configuration export from old tenant → import to new (Auth0 deploy CLI or terraform-provider-auth0)
- Application registrations migrated with new client IDs / secrets
3. Phase 3 — DNS + application cutover
1-2 weeks
- Custom domain CNAME re-pointed (or kept the same if tenant carries forward)
- Application code updated with new tenant URLs (if changed)
- Coexistence window honored for users with active sessions
What lives where.
| Capability | Source (Auth0) | Target (Okta) |
|---|---|---|
| Authentication | Auth0 Universal Login | Okta CIC Universal Login Identical product |
| Rules / Actions | Auth0 Rules + Actions | Okta CIC Actions Rules are deprecated in CIC; migrate to Actions before swap |
| Multi-tenancy | Auth0 Organizations | Okta CIC Organizations Same feature, same shape |
| Database connections | Auth0 DB | Okta CIC DB Direct export / import |
| Custom domains | Auth0 custom domain | CIC custom domain May reuse existing CNAME |
What moves, what doesn’t.
User export + import
Use Auth0 Management API to export users. Import via the same API into the new tenant. Password hashes are preserved when migrating between Auth0 / CIC tenants — users do not need to reset.
Tenant configuration
Use the Auth0 deploy CLI (a0deploy) or the terraform-provider-auth0 to export tenant configuration as code and import to the new tenant.
Tokens + session continuity
Outstanding refresh tokens issued by the old tenant won't work against the new tenant. Plan a coexistence window or force re-authentication at cutover.
The 7-step cutover.
- 01Verify new CIC tenant configured identically (apps, connections, rules → actions, custom domain)
- 02DNS TTL reduced to 5 minutes ahead of swap
- 03Comms to customers about possible re-authentication
- 04Cut DNS / app config to new tenant
- 05Monitor sign-in success rate via CIC dashboard
- 06Decommission old tenant after retention window (typically 30-90 days)
What teams find out the hard way.
Auth0 Rules are deprecated; CIC uses Actions
If you still have classic Rules running, migrate them to Actions before the swap. Rules won't carry forward and silently dropped logic creates security gaps.
Custom code in extensions
Auth0 Extensions (Authentication API Webhooks, custom DB scripts) may need code review when moving to CIC. Most carry forward; edge cases don't.
Tenant URLs may change
If the tenant URL changes (yourname.auth0.com → yourname.okta.com), application code referencing the URL must be updated. Custom domains mitigate this.
Questions we get on this migration.
Is this really a migration if Okta owns Auth0?
Commercially yes; technically minimal. The product is the same. The migration is mostly a contract + tenant transition.
Will users need to reset their passwords?
No. Password hashes are preserved across Auth0 / CIC tenants.
We’ve led this migration. More than once.
