Before cancelling your old hosting plan, make sure you have a complete copy of your website files, database and email accounts. A recent backup is your most important safety net.
Next, the website is copied to the new server and tested through a temporary address before your domain's direction is changed. This confirms everything works correctly before your visitors see any change at all.
The final step is updating your DNS records so your domain points to the new server. Because DNS changes take time to propagate, we typically keep both servers active for a few days, so there is no downtime whatsoever for your visitors.
