Magento Upgrade from 2.2 to 2.4.5 - Big trouble with PHP version!
i spent 1 week trying to upgrade magento from version 2.2 to 2.4. In order to proceed I have downloaded and I am using composer 1. My PHP version is 7.1 - Perfectly compatible with Magento 2.2. With composer 1 I was able to get a "composer require" without errors. I then launched the "composer update" command but it goes into error due to the lack of php 7.4 or higher. Now: I could also update the php and finish the "composer update" but then the "magento/upgrade" will not work because it is the one of magento 2.2 which only works with php 7.1
