Set up the connections
Use the provider-specific credential guides before you preview, then keep the migration checklist beside the cutover plan.
How the move works
- 1
Connect Rackspace
Connect Rackspace with read-only access (Cloud account username and API key).
- 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 Rackspace 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 Rackspace
- Apex NS and SOA records are managed by Rackspace and can't be changed.
- PTR records are only managed through Rackspace's reverse-DNS API for its own cloud devices, so they aren't migrated.
- TTLs below 300 seconds are raised to 300.
- Rackspace removes quote and backslash characters from TXT data.
- Changes run as asynchronous Rackspace jobs; we wait for each job to finish, so large plans take longer.
- New domains use the connection's SOA contact email, or hostmaster@<domain> when none is set.
- Subdomains that Rackspace hosts as separate domains are listed as their own zones.
Access we need: Use a dedicated account user with the DNS Admin product role (dnsaas:admin). DNS Creator can't delete records, and DNS Observer is read-only, which is enough for a source connection.
Good to know about Bunny
- Redirect records (BUNNY_DNS_RDR) and Pull Zone records (BUNNY_DNS_PZ, by pull zone ID) are migrated. Script and Flatten records, and disabled records, aren't.
- A Pull Zone record only works if the pull zone ID exists in the destination bunny.net account.
- 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 Rackspace 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 Rackspace?
No. We never write to Rackspace. 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.
