Changing Hosting Providers
If you are changing hosting providers, then you can keep your current Cloudflare account and update the IP information under Cloudflare DNS Settings. All of the information in your Analytics and Threat Control will not be affected. If you are a Business Pro or Reseller client and have been using Cloudflare Railgun, unless your new registrar also supports Railgun, you will no longer have it as a service.
If you are currently using Cloudflare through one of Cloudflare’s hosting partners and are leaving the hosting provider, then you need to disable Cloudflare from your control panel. Once you are set up with your new hosting provider, for example HostPapa, you can enable Cloudflare right from your HostPapa control panel (cPanel). If you left your hosting provider without disabling Cloudflare first, then you will need to contact Cloudflare directly. If you disable Cloudflare and re-signup for it, the information in your Analytics and Threat Control will restart. The information cannot be merged.
If you are changing registrars, you need to deactivate Cloudflare and revert your name servers back to your old registrar. Then, you must go through the process of changing registrars; once that is completed, re-add your site to Cloudflare. The information in your Analytics and Threat Control will restart. The information cannot be merged.
