It is possible that you will see no extensions in MagentoConnect Manager. This means that you have just uploaded the files without using PEAR downloader. In that case enter magento-core/Mage_All_Latest in the extension key field and click Install button. This will install all latest MagentoConnect core packages on top of existing files and will allow future upgrades through MagentoConnect.
