Do I have to upgrade from Magento 1 to Magento 2
Magento 1 was EOL (end-of-life) in June 2020. This means that Magento no longer officially supports the platform, and they issued the very last security patch on June 22, 2020. Since then, there have been multiple Magento websites hacked, ransom-wared, and otherwise exploited by criminals who are all too aware of the vulnerability of Magento 1 sites that remain in the wild. Please read Online store hacked in largest campaign to date for evidence of this occurring already.
