Transfering to new hosting

I’ve planned to change hosting and made ready. my hosting is ready and I have set up everything, My domain is in cloudflare. but it is loading from old server data. Do I need to change first nameservers to new hosting nameservers and then to cloudflare hosting?
Please tell me the procedure when changing the hosting.

You need to update your DNS records in the Cloudflare Dashboard. They should match the DNS records at your new host.

Thanks it’s working now. areicon.com. I just changed the server IP address on DNS and worked. How can we get the correct SRV records of hosting?
