কীভাবে ডোমেইন ট্রান্সফার করবেন Without ওয়েবsite অথবা ইমেল Downtime
A ডোমেইন transfer should not usually cause website অথবা email downtime if আপনার nameservers এবং DNS recঅথবাds remain active. Befঅথবাe transferring, identify the DNS provider, back up all recঅথবাds, avoid unnecessary nameserver অথবা MX changes during transfer, এবং prepare replacement DNS if the old registrar may stop DNS সেবা after transfer out.
Who This Guide Is Fঅথবা
This guide is fঅথবা:
· Businesses that cannot affঅথবাd website downtime
· Users transferring ডোমেইনs to NiceNIC
· Agencies protecting client sites এবং mailboxes
· হোস্টিং providers guiding customers
· ডোমেইন investঅথবাs using parking অথবা lএবংing pages
Befঅথবাe You Start
Befঅথবাe you start, prepare:
· Current DNS provider identified
· Current nameservers recঅথবাded
· Full DNS backup saved
· MX, SPF, DKIM, এবং DMARC backed up
· Old registrar DNS continuity checked
· হোস্টিং এবং email providers kএখনn
· DNSSEC status checked
· Transfer eligibility confirmed
Step-by-Step Instructions
Step 1: Separate রেজিস্ট্রার Transfer From হোস্টিং Migration
A registrar transfer moves ডোমেইন registration management, not website files, databases, email inboxes, অথবা hosting accounts.
· Do not combine multiple migrations without a plan
· Keep hosting এবং email stable during transfer
Step 2: Identify DNS Provider
পরীক্ষা করুন nameservers to see wএখানে DNS is hosted.
· রেজিস্ট্রার DNS
· হোস্টিং DNS
· CDN DNS
· Third-party DNS
· Private nameservers
Step 3: Back Up DNS Recঅথবাds
Save all website, email, verification, SSL, CDN, এবং app recঅথবাds.
· A, AAAA, CNAME, MX, TXT, CAA, SRV
· SPF, DKIM, DMARC
· DS recঅথবাds if DNSSEC is enabled
Step 4: পরীক্ষা করুন Old রেজিস্ট্রার DNS Risk
যদি DNS is hosted by the old registrar, confirm whether it continues after transfer out.
· যদি not, recreate DNS elsewএখানে befঅথবাe transfer
· Do not cancel old সেবাs early
Step 5: Keep নামservers Stable
যদি current DNS is reliable, avoid changing nameservers during transfer.
· Change DNS befঅথবাe অথবা after transfer, not during, unless planned
Step 6: Protect ইমেল Recঅথবাds
নিশ্চিত করুন MX, SPF, DKIM, DMARC, autodiscover, এবং provider verification recঅথবাds.
· ইমেল downtime often starts with missing MX recঅথবাds
Step 7: Submit the Transfer
Unlock the ডোমেইন, use the cঅথবাrect EPP code, এবং submit through NiceNIC.
· Monitঅথবা approvals
· Avoid unrelated changes
Step 8: Verify After Completion
পরীক্ষা করুন website, www, subডোমেইনs, email sending এবং receiving, SSL, DNSSEC, redirects, এবং renewal settings.
· Review privacy এবং lock settings too
Troubleshooting
ওয়েবsite Down After Transfer
Possible reasons:
· Old registrar DNS stopped
· A অথবা CNAME missing
· নামservers changed
· DNSSEC failure
What to do:
· Restঅথবাe DNS from backup
· পরীক্ষা করুন nameservers এবং DS recঅথবাds
· যোগাযোগ hosting if DNS points cঅথবাrectly
ইমেল Stopped Wঅথবাking
Possible reasons:
· MX missing
· SPF/DKIM/DMARC missing
· Old DNS stopped
What to do:
· Restঅথবাe MX first
· Restঅথবাe TXT recঅথবাds
· পরীক্ষা করুন email provider panel
DNSSEC Breaks Resolution
Possible reasons:
· Old DS recঅথবাds remain
· নতুন DNS provider keys differ
What to do:
· অপসারণ করুন incঅথবাrect DS recঅথবাds অথবা add cঅথবাrect DS values
· Verify validation

প্রায়শই জিজ্ঞাসিত প্রশ্ন
1. Will transfer make my site offline?
Usually no, if DNS remains active.
2. Will business email stop?
It should continue if MX এবং email DNS recঅথবাds remain cঅথবাrect.
3. Should I change nameservers befঅথবাe transfer?
Only if old registrar DNS may stop অথবা you have a planned DNS migration.
4. What recঅথবাds should I back up?
সব website, email, TXT, CAA, SRV, verification, CDN, এবং DNSSEC recঅথবাds.
5. Can NiceNIC move my hosting automatically?
না. হোস্টিং migration is separate.
6. What if old registrar DNS disappears?
Restঅথবাe recঅথবাds at NiceNIC অথবা another DNS provider.
7. Does DNS propagation cause tempঅথবাary differences?
হ্যাঁ, especially after nameserver changes.
8. What if DNSSEC is enabled?
Review DS recঅথবাds befঅথবাe changing DNS providers অথবা nameservers.
