How the move works
- 1
Connect Gcore
Connect Gcore with read-only access (Permanent API token).
- 2
Connect Bunny
Connect Bunny (Account API key). 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 Bunny
We snapshot the Bunny zone, write in batches, and leave Gcore untouched.
- 5
Verify
We query Bunny'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 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.
Good to know about Bunny
- Pull Zone, Script and Flatten records, and disabled records, aren't migrated. Redirect records are read as URL redirects to recreate by hand.
- Records that use smart routing (latency or geolocation) or CDN acceleration are flagged and never changed by us.
- An apex CNAME is flattened by Bunny, so it can point at any hostname.
Access we need: The account API key has full access. There is no read-only key, so rotate it after the migration.
Questions
Will there be downtime moving from Gcore to Bunny?
Not if both providers serve the same answers during the switch. The records are copied to Bunny 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 Gcore?
No. We never write to Gcore. 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 Bunny and publish its new DS record. The cutover plan walks you through each step.
