Hello guys,
I have multiple domains in multiple accounts that need to be migrated into one unified account.
My issue is that these domains/zones are production and any downtime causes business impact. Therefore I am looking for the smoothest way of migrating these zones from Account A to Account B.
The challenge is mainly for the proxied traffic. Proxied traffic is using custom security rules, LB records, Spectrum records, Tunnels and more.
Please let me know if any of you have experienced this, we need minimum to 0 downtime and possibility to rollback in case of unexpected errors while migrating.
CloudFlare Support are not very useful till now. I'm not looking for someone to do it for me, just some guidance on best practice for such migration.
Trying to avoid preparing all the zone configuration on the new acount and just changing the NS records on my registrar as it might cause downtime and in case of rollback it would take a lot of time due to NS records being cached.(Not all registrars support decreasing TTL for NS records)
