How to Transfer a Domain Without Website or Email Downtime

A domain transfer should not usually cause website or email downtime if your nameservers and DNS records remain active. Before transferring, identify the DNS provider, back up all records, avoid unnecessary nameserver or MX changes during transfer, and prepare replacement DNS if the old registrar may stop DNS service after transfer out.

Who This Guide Is For
This guide is for:
· Businesses that cannot afford website downtime
· Users transferring domains to NiceNIC
· Agencies protecting client sites and mailboxes
· Hosting providers guiding customers
· Domain investors using parking or landing pages

Before You Start
Before you start, prepare:
· Current DNS provider identified
· Current nameservers recorded
· Full DNS backup saved
· MX, SPF, DKIM, and DMARC backed up
· Old registrar DNS continuity checked
· Hosting and email providers known
· DNSSEC status checked
· Transfer eligibility confirmed

Step-by-Step Instructions
Step 1: Separate Registrar Transfer From Hosting Migration
A registrar transfer moves domain registration management, not website files, databases, email inboxes, or hosting accounts.
· Do not combine multiple migrations without a plan
· Keep hosting and email stable during transfer
Step 2: Identify DNS Provider
Check nameservers to see where DNS is hosted.
· Registrar DNS
· Hosting DNS
· CDN DNS
· Third-party DNS
· Private nameservers
Step 3: Back Up DNS Records
Save all website, email, verification, SSL, CDN, and app records.
· A, AAAA, CNAME, MX, TXT, CAA, SRV
· SPF, DKIM, DMARC
· DS records if DNSSEC is enabled
Step 4: Check Old Registrar DNS Risk
If DNS is hosted by the old registrar, confirm whether it continues after transfer out.
· If not, recreate DNS elsewhere before transfer
· Do not cancel old services early
Step 5: Keep Nameservers Stable
If current DNS is reliable, avoid changing nameservers during transfer.
· Change DNS before or after transfer, not during, unless planned
Step 6: Protect Email Records
Confirm MX, SPF, DKIM, DMARC, autodiscover, and provider verification records.
· Email downtime often starts with missing MX records
Step 7: Submit the Transfer
Unlock the domain, use the correct EPP code, and submit through NiceNIC.
· Monitor approvals
· Avoid unrelated changes
Step 8: Verify After Completion
Check website, www, subdomains, email sending and receiving, SSL, DNSSEC, redirects, and renewal settings.
· Review privacy and lock settings too

Troubleshooting
Website Down After Transfer
Possible reasons:
· Old registrar DNS stopped
· A or CNAME missing
· Nameservers changed
· DNSSEC failure
What to do:
· Restore DNS from backup
· Check nameservers and DS records
· Contact hosting if DNS points correctly
Email Stopped Working
Possible reasons:
· MX missing
· SPF/DKIM/DMARC missing
· Old DNS stopped
What to do:
· Restore MX first
· Restore TXT records
· Check email provider panel
DNSSEC Breaks Resolution
Possible reasons:
· Old DS records remain
· New DNS provider keys differ
What to do:
· Remove incorrect DS records or add correct DS values
· Verify validation

FAQ
1. Will transfer make my site offline?
Usually no, if DNS remains active.
2. Will business email stop?
It should continue if MX and email DNS records remain correct.
3. Should I change nameservers before transfer?
Only if old registrar DNS may stop or you have a planned DNS migration.
4. What records should I back up?
All website, email, TXT, CAA, SRV, verification, CDN, and DNSSEC records.
5. Can NiceNIC move my hosting automatically?
No. Hosting migration is separate.
6. What if old registrar DNS disappears?
Restore records at NiceNIC or another DNS provider.
7. Does DNS propagation cause temporary differences?
Yes, especially after nameserver changes.
8. What if DNSSEC is enabled?
Review DS records before changing DNS providers or nameservers.
