Moving 50 domains without losing a day of DNS
Bro so I had to move 50 domains from one registrar to another wey, old one jacked prices 40% and I was not gonna pay that. Biggest fear was DNS going down even for hours because some of these are client sites and they do NOT forgive downtime.
My playbook:
- export zone files 2 weeks before
- set TTLs to 300 on everything 1 week before
- create duplicate zones at new registrar but dont point NS yet
- transfer domains in batches of 10
- update NS at old registrar LAST so cutover is instant
- monitor with pingplot from 3 locations
Took 3 days total but zero DNS downtime. What did I miss?
