When moving off WordPress makes sense
WordPress is a solid platform, and it is not always the wrong choice. It shines when a team publishes often and needs a familiar editor. For many small business sites, though, the pages rarely change, and the site carries a database, a theme, and a dozen plugins that all need updates and security patches.
If that describes your site, a modern statically generated site can serve the same pages faster and with far less to maintain. I will tell you honestly if staying on WordPress is the better call for you.
