Magento 2 Upgrade & QA

My store is currently on Magento 2.4.6 and I need it moved to the latest Magento 2 release. The job is not just a straight-forward core update; I also expect a full round of post-upgrade testing and any fixes required to keep daily sales flowing smoothly. Scope of work Update site, extensions and apply any fixes required. The finished job should mean the site is working without issue as it does now We provide the updated server to work on the upgrade. The project is complete when the live site processes real orders without errors and all tests pass.
