The first and most important step in any application upgrade is creating a backup of your files and database. This way you will be able to restore your site if the upgrade does not complete successfully.
In versions up to 1.4, the Magento command line tool is called pear. In Magento 1.5 this tool has been renamed to mage. So the first thing you need to do is upgrade pear to mage. To do this, you need to cd (change directory) to your Magento installation folder.
For example, if your Magento is installed in a folder called store, you need to type the following once you log in to your account via SSH:
Then you need to execute this command:
./pear upgrade -f magento-core/Mage_All_Latest-stable
You will see lots of lines notifying you about packages being downloaded. You may also see some warnings and errors, but in most cases you can safely disregard them as they will not disrupt the upgrade process.
Once the packages have been upgraded, you will see upgrade ok messages notifying you that the upgrades have been completed successfully:
You should now have the mage tool available in the Magento installation directory. To be able to use it, you need to make it executable:
chmod 755 mage
Now you can see the available commands by typing:
To be able to use the mage tool, you need to initialize it first. This is done by executing:
./mage mage-setup .
The next step is to sync your installed extensions with the new Magento Connect version 2.0. You can do that by executing:
Now you are ready to complete the Magento upgrade. To upgrade your Magento to the latest version, you need to execute:
./mage upgrade-all --force
This will download the latest package versions, upgrading your existing ones and finalizing the Magento upgrade:
Your Magento has been upgraded successfully. You can now go to your store and review the upgraded version. You may need to flush the Magento cache to see the changes.
