I would like to upgrade my magento store from 1.1.2 to 1.3.3
I have gone through system->magento connect-> magento connection manager and clicked check for updates button. But it did not show any upgrades, so i cant upgrade to 1.3.3
Download the version you want to upgrade to from http://www.magentocommerce.com/download under the ‘Release Archives’ tab then copy the files in the archive over your site (of course you’ll do this on a dev/test server first!). When happy apply the changes to your live site. I’d also suggest doing incremental upgrades up to at least v1.6.x . Do these bit by bit on dev then live until you are up to date. Do not just try an upgrade direct to 1.6.x or later in one go!
