Migrate your WordPress site to Krystal
Krystal provides Softaculous and Installatron application installers - both of which have the ability to import a remote WordPress installation - which makes migrating your WordPress site to Krystal a breeze.
They can both be accessed from within your hosting account's cPanel and we have separate guides on using each of them:

Once you've migrated your site you'll want to test it before making changes to your DNS.
Finally you'll want to update your DNS - either by switching the name servers for your domain to Krystal's or by adding appropriate A records to point at your Krystal servers IP address.
