Cloudflare DNS Gcore DNS

Migrate DNS from Cloudflare to Gcore.

9 record types move as they are. 4 things work differently at Gcore, and the preview shows exactly which of your records they affect.

Free preview. Read-only. Nothing changes until you apply.

Generated from the same provider capability data the migration engine uses.

Proxied records lose the CDN

Gcore has no equivalent of Cloudflare's proxy. Proxied records move as plain records pointing at your origin, which exposes the origin IP. Put a CDN in front before cutting over if that matters.

"Auto" TTLs get a real value

Cloudflare's automatic TTL has no equivalent, so those records get Gcore's default of 3600s.

Domains registered at Cloudflare must transfer out

Cloudflare Registrar only allows Cloudflare's nameservers. If the domain is registered there, transfer it to another registrar before switching.

A typical Cloudflare zone at Gcore

Example records for example.com. Open any flagged row to read why it changed.

Cloudflare Gcore

  • ReviewCNAME@

    app.example-host.net.

    TTL was "auto". Set to 3600s.

  • ExactMX@

    10 mx1.mail.example.net. +1

  • ExactTXT@

    "v=spf1 include:_spf.example.net -all"

  • ExactCAA@

    0 issue "letsencrypt.org"

  • ExactTXT_dmarc

    "v=DMARC1; p=reject; rua=mailto:dmarc@example.com"

  • ExactSRV_sip._tls

    100 1 443 sip.example.net.

  • ExactAmail

    203.0.113.25

  • ReviewAshop

    203.0.113.10

    TTL was "auto". Set to 3600s.

  • ExactCNAMEwww

    example.com.

How the move works

  1. 1

    Connect Cloudflare

    Connect Cloudflare with read-only access (Scoped API token).

  2. 2

    Connect Gcore

    Connect Gcore (Permanent API token). Write access is only used when you apply.

  3. 3

    Review the preview

    Check every record marked Review or Unsupported. Each one explains what changes and why.

  4. 4

    Apply to Gcore

    We snapshot the Gcore zone, write in batches, and leave Cloudflare untouched.

  5. 5

    Verify

    We query Gcore's own nameservers for every record and compare the answers before you switch.

  6. 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 Cloudflare

  • Proxied (orange-cloud) records hide the origin IP. Moving them to another provider sends traffic straight to the origin.
  • Apex CNAMEs are flattened by Cloudflare. Other providers need an ALIAS record or static A/AAAA records instead.
  • Cloudflare Registrar only allows Cloudflare nameservers, so domains registered there must be transferred out first.

Access we need: Zone → DNS → Read for the preview, Zone → DNS → Edit to apply.

Good to know about Gcore

  • Record sets that use GeoDNS or balancing filters, failover health checks, answer metadata or disabled answers are flagged and never changed by us.
  • SRV records can't have an empty target, and PTR records only work in reverse-DNS zones.
  • ALIAS records are written as CNAMEs, which Gcore flattens at the zone apex.

Access we need: A permanent API token whose role can manage DNS. Gcore tokens can't be limited to read-only DNS.

Questions

Will there be downtime moving from Cloudflare to Gcore?

Not if both providers serve the same answers during the switch. The records are copied to Gcore 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 Cloudflare?

No. We never write to Cloudflare. 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 Gcore and publish its new DS record. The cutover plan walks you through each step.

What happens to Cloudflare proxied records?

They move as ordinary records pointing at your origin server, because Gcore can't proxy traffic. The preview lists every proxied record and the IP it would expose.
