Steps to update the bootstrap version in an existing project

My current project was built using Bootstrap 3.3.6 classes, but now I want to take advantage of the features offered by Bootstrap 5.2. However, simply changing the version of Bootstrap isn't as easy as it sounds. What is the most effective way to upgrade without having to rewrite all of the code?

I attempted to switch to the latest version CDN, but unfortunately, this caused my entire project to break.

Answer №1

For helpful information, review this document: https://getbootstrap.com/docs/5.0/migration/

Following these modifications, your project may experience hiccups. Simply adjust the class names in your HTML code to restore functionality. Be prepared for some effort as you will need to inspect all of your code carefully.

Answer №2

A new tool has been developed to help with the transition from Bootstrap 4 to Bootstrap 5. This script scans all pages and templates within a specified folder, automatically updating all Bootstrap 4 classes to Bootstrap 5 classes. Additionally, it replaces deprecated components like .jumbotron and .media with utility classes, updates data attributes like data-toggle and data-target, and ensures that all Bootstrap v4 CDN links are updated to the latest version of Bootstrap v5.
