Pre-Upgrade Checklist: Essential Preparations

A successful Magento upgrade requires meticulous planning and preparation. This checklist outlines the essential steps to take before starting the upgrade process:

1. Backup Everything

This is the most crucial step. Before making any changes to your Magento installation, create a complete backup of your database and file system. This backup will serve as a safety net in case anything goes wrong during the upgrade process. Use a reliable backup solution and store the backup in a secure location.

Why is this important? A backup allows you to quickly restore your store to its previous state if the upgrade fails or introduces unexpected issues. Without a backup, you risk losing valuable data and experiencing significant downtime.

2. Audit Your Extensions

Magento’s ecosystem of extensions is vast, but not all extensions are created equal. Before upgrading, thoroughly audit all the extensions installed on your store.
