How the move works

1
Connect Namecheap
Connect Namecheap with read-only access (API user + API key, with our egress IP allow-listed).
2
Connect Porkbun
Connect Porkbun (API key + secret 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 Porkbun
We snapshot the Porkbun zone, write in batches, and leave Namecheap untouched.
5
Verify
We query Porkbun'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 Namecheap

Namecheap's API replaces the whole host list on every write, so we always read, merge and then write.
SRV records can't be managed through the API.
URL redirect records are Namecheap-specific and aren't real DNS records.

Access we need: API access enabled under Profile → Tools, with our static IP added to the allow-list.

Good to know about Porkbun

API Access must be turned on per domain, and only domains registered at Porkbun can be managed.
The minimum TTL is 600 seconds and a zone holds at most 2,500 records.
URL forwarding is not migrated; the ALIAS/CNAME records Porkbun creates for it are copied as plain records.

Access we need: Porkbun keys have no read-only mode. Restrict the key to the domains you move and turn on API Access for each of them.

Questions

Will there be downtime moving from Namecheap to Porkbun?

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

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