How the move works
- 1
Connect Gandi
Connect Gandi with read-only access (Personal access token (legacy API key also accepted)).
- 2
Connect Vercel
Connect Vercel (Access token (+ team ID)). Write access is only used when you apply.
- 3
Review the preview
Check every record marked Review or Unsupported. Each one explains what changes and why.
- 4
Apply to Vercel
We snapshot the Vercel zone, write in batches, and leave Gandi untouched.
- 5
Verify
We query Vercel's own nameservers for every record and compare the answers before you switch.
- 6
Switch nameservers
Lower TTLs a day or two ahead, remove any DS record if DNSSEC is on, then point the domain at the new nameservers at your registrar.
Good to know about Gandi
- LiveDNS only hosts zones for domains in your Gandi organization, so zones can't be created for domains registered elsewhere.
- ALIAS records are only allowed at the zone apex; TTLs must be between 300 seconds and 30 days.
- Apex NS records are managed by Gandi and are left untouched.
Access we need: A token with “Manage domain name technical configurations”, scoped to the domains you move. Gandi has no read-only LiveDNS permission.
Good to know about Vercel
- Records Vercel adds for project domains (such as the apex ALIAS and CAA) are read with a comment and never changed by us. Edit them in the project's domain settings.
- Domains must already be added to the Vercel account or team. We can't create them.
- Vercel DNS doesn't support DNSSEC, and the minimum TTL is 60 seconds.
Access we need: An access token scoped to the team that owns the domains. Vercel tokens can't be read-only.
Questions
Will there be downtime moving from Gandi to Vercel?
Not if both providers serve the same answers during the switch. The records are copied to Vercel and verified before you change nameservers, so resolvers get the same answer from either side while caches expire.
Do I have to delete anything at Gandi?
No. We never write to Gandi. Keep the old zone for a week after cutover so you can switch back instantly if anything looks wrong.
What about DNSSEC?
If DNSSEC is on, remove the DS record at your registrar and wait for it to expire before switching nameservers. Then enable DNSSEC at Vercel and publish its new DS record. The cutover plan walks you through each step.
