When installing the Comet Cache plugin, Comet Cache will automatically detect and preserve your existing Quick Cache settings. Once Comet Cache has been activated, Quick Cache will be deactivated. All of this happens automatically; all you need to do is install the Comet Cache plugin.

There are two ways to install Comet Cache:

Installing Comet Cache via the WordPress Dashboard

1. Log in to your WordPress Dashboard and go to Plugins → Add New in the sidebar and then search the Plugin Repository for "Comet Cache".
2. Click the "Install Now" button for the Comet Cache plugin; it should be at the top of the search results.
3. Click the "Activate Now" link when Comet Cache finishes downloading
4. (Optional Step) Now that you've deactivated the Quick Cache plugin, you can also Delete it, as there is no need to have both Quick Cache and Comet Cache installed.

Installing Comet Cache via Downloaded Zip File

1. Download the Comet Cache plugin from WordPress.org or from cometcache.com
2. Log in to your WordPress Dashboard and Visit Plugins → Add New
3. Click the Upload Plugin button
4. (Optional Step) Now that you've deactivated the Quick Cache plugin, you can also Delete it, as there is no need to have both Quick Cache and Comet Cache installed.

That's it! If you had Quick Cache installed prior to installing Comet Cache, you should see a migration message like the one below:

You'll also now see a new "Comet Cache" icon in the WordPress Dashboard Sidebar:
