Magento – Shopping Cart

Upgrading Magento Shopping Cart By SSH Access

Upgrading is just as simple as installation. Go to the directory of the Magento
installation you wish to upgrade and run the following:
./pear mage-setup .
./pear install magento-core/Mage_All_Latest
rm -rf downloader/pearlib/cache/* downloader/pearlib/download/*
After we’ve executed the previous command, the Magento installation will be
upgraded. We’ll just need to access it at its appropriate URL, as with the other
methods, and all MySQL related updates will take place.
If we need to clear our cache and sessions, we can use the following command:
rm –rf var/cache/* var/session/*
