Upgrading Magento
We’ve been asked how easy it is to upgrade Magento. So, there I was thinking, hey – they’ve got this Magento Connect Manager, a few clicks and we’re done. Wrong. Very wrong. Go on to read the tale of the dreaded “500 Internal Server Error” problem (= your permissions are wrong), a small issue with Url.php and why not taking backups is really bad for your health.
The upgrade test was carried out on a standard Magento v1.3.0 install on a Linux with PHP5.2.9. Note that Magento does not allow gradual upgrades, at least not via the Magento Connect Manager. If you use the Manager, it’s all or nothing.
