Before doing an upgrade, this program is used to find potential code issues and repair them. In other words, it is a command-line tool that locates important problems, errors, and warnings in codes and fixes them before upgrading. The store owner can use the Upgrade Compatibility Tool to detect potential customizations in advance of upgrading Magento Commerce, which makes the process more transparent and lowers the cost of performing regular upgrades. The Upgrade Compatibility Tool is currently available in alpha form and can be obtained as a composer from the Magento repository.
