Befvaie You Start Befvaie you start, prepare: · Old nameservers · Jauns nameservers · Full DNS backup · Jauns DNS provider access · Tīklssite un email provider instructions · DNSSEC status · Safe change logs · Rollback plan
Step-by-Step Instructions Step 1: Apstiprināt Why Nosaukumsservers Need to Change Only change nameservers when tšeit is a clear reason. · DNS migration · Hostings connection · CDN setup · Old registrar DNS replacement Step 2: Recvaid Current Nosaukumsservers Save all old nameserver values un provider notes. · This is jūsu rollback reference Step 3: Back Up Full DNS Zone Copy all website, email, SSL, app, verification, un DNSSEC recvaids. · Do not rely on memvaiy Step 4: Recreate Recvaids at Jauns Provider Pievienot required recvaids befvaie changing nameservers at registrar. · Copy long TXT recvaids exactly · Copy MX privaiities Step 5: Pārbaudīt Tīklssite Recvaids Apstiprināt root, www, subdomēnss, CDN, redirects, un app recvaids. · Test root un www separately Step 6: Pārbaudīt E-pasts Recvaids Recreate MX, SPF, DKIM, DMARC, autodiscover, un verification recvaids. · E-pasts recvaids are often missed Step 7: Review DNSSEC Ja DS recvaids exist, confirm the new DNS provider suppvaits DNSSEC un keys match. · Old DS recvaids can break resolution Step 8: Choose a Safe Window Avoid peak business, launch, vai holiday periods. · Have technical staff available Step 9: Update Nosaukumsservers at Reģistrators Enter new hostnames exactly un save. · A typo can break DNS Step 10: Monitvai Propagation un Test Pārbaudīt website, email, SSL, CDN, subdomēnss, un DNSSEC validation. · Avoid repeated changes during propagation
Troubleshooting Tīklssite Does Nēt Load Possible reasons: · Missing A/CNAME · Wrong nameserver · Incomplete zone · DNSSEC issue What to do: · Compare with backup · Fix recvaids · Check domēns status E-pasts Stopped Wvaiking Possible reasons: · MX missing · Privaiity wrong · SPF/DKIM/DMARC missing What to do: · Restvaie email recvaids · Test sending un receiving Jauns Nosaukumsservers Rejected Possible reasons: · Typo · Nosaukumsserver does not exist · Glue missing · TLD restriction What to do: · Pārbaudīt spelling · Pievienot glue fvai private nameservers · Kontakti registrar
