Dear all experts! I'm little bit stuck on some point, I want to transfer my website hosting from one host to amazon server and i want no downtime. Can anyone please explain me is there any possible solution so I can transfer my web-hosting from one server to amazon servers without downtime. Thanks
Well, when transferring domains it would be some downtime caused by dns propagation, but with fast dns services it would be minutes, not more
Agreed to Accuratist ... you can use Cloudflare DNS temporarily for moving. It will be so fast and very very low downtime.
You can do it without downtime. Firstly build your site at the new place, check that it works by manipulating your "hosts file" and then change your DNS.
