I created a copy of my site on xammp as a Development version to test the upgrade from 18.104.22.168 to 22.214.171.124 . But when I went forth and carried out the upgrade, I got no errors although going to magento connect my version shows 126.96.36.199. Looking at core_resources table the data_version numbers match 188.8.131.52. So looks like a failed upgrade.
I used the method of replacing the app > core folder with the new one. And the frontend base default folder, Then mage.php file with new one. From here I deleted local.xml and went through installation. Could you guys help with what is the best way to upgrade and where did I go wrong?
