Moving Magento? Remember to run this command
If your working with Magento and have to move an installation, you will want to make sure it’s locally installed PEAR repository is updated as well. It stores a bunch of first install paths in a serialized PHP file. Instead of manually editing them, you can simply run this from the root install of your Magento:
./pear mage-setup
That should update everything to work as expected for updates and the like.
