Best Practices Before Updating CMS, Themes, and Plugins

1. Create a Full Backup

• Back up the database and files before updating.

• Use backup plugins like UpdraftPlus (WordPress), Akeeba Backup (Joomla), or Backup and Migrate (Drupal).

• Store backups in multiple locations (cloud, local, and external storage).

2. Test Updates in a Staging Environment

• Use a staging site to test updates before applying them to the live site.

• Many hosting providers offer 1-click staging environments.

• If a staging site isn’t available, create a local copy using XAMPP or LocalWP.

3. Check Changelogs and Compatibility

• Review release notes for CMS core, themes, and plugins before updating.

• Ensure updates are compatible with your existing setup.

• Check for known conflicts or issues reported by other users.

• Disable caching and performance plugins before updates to avoid conflicts.
