I have an ISP switchover that I am doign this weekend as well as switching over domain name hosting on 3 domains. Looking for some advice/tips to ensure this goes as smoothly as possible.
I have created the 3 DNS zones on a public DNS server with update ip addressed of the new ISP. I have the logins for the 3 registrars for the 3 domains that i will need to switch over.
Should I switch the ISP and registrar NS records all at once or space it out a bit.
Thanks for your help
