The System Upgrade tool can be used to upgrade your Magento installation from the Admin. The upgrade is a three-step process that should take place during off-peak hours. Before upgrade takes place, your store is put into maintenance mode, checked for readiness, and backed up.
- Only the primary account holder is authorized to download code from the repository.
- The authorization keys that are used to download code must be generated from the primary account.
- The merchant or developer must submit a ticket to Support and request authorization for the download.
Caching and Reindexing
Always flush the cache when upgrading from one version of Open Source or Commerce to another. Two upgrade examples include: upgrading from Magento Open Source 2.2.X to 2.3.X and upgrading from Magento Open Source 2.3.X to Magento Commerce 2.3.X.
Important: Always flush the cache after installing or upgrading Magento, or any extensions and modules.
For developer information on upgrades, see the DevDocs Command Line Upgrade. The upgrade instructions include scripts to help run and complete your upgrades. These steps require developer assistance.
