title: How to upgrade a liferay theme from 7.0 to 7.4?
body: <p>I'm following the official tutorial to update a theme from 7.0 to 7.2 <a href="https://help.liferay.com/hc/es/articles/360029316831-Running-the-Upgrade-Task-for-7-0-Themes" rel="nofollow noreferrer">https://help.liferay.com/hc/es/articles/360029316831-Running-the-Upgrade-Task-for-7-0-Themes</a>, the process is successful but I need to update to liferay 7.4 and I can't find official documentation or information on how to continue from here, I try to deploy the war on my local server with 7.4 but it says which is not compatible with this version of Liferay. Can someone guide me?</p>
