With both servers running cPanel/WHM it should be just that simple to get started. Import your backup and then start repointing DNS.

Once your files and configuration are in place on the new server you can test the configuration before you switch over DNS by creating a hosts file entry for the domain(s) you want to test. Just make sure you remove the entries once you’re done testing.

On Windows the hosts file can be found in C:\Windows\system32\drivers\etc and on Linux and Mac it can be found at /etc/hosts. In both cases it is simply a domain/subdomain name and IP address to map it to. This will override the results your computer receives from the DNS servers (this is why it’s important to remove when your done since otherwise if an issue occurs in the future you may not be able to see it and it could lead to a lot of unnecessary troubleshooting).
