I am new to magento. If I use the Package upgrade available through magento connect downloader do I need to backup and overwite my custom files as in the upgrade roadmap when upgrading a full magento installation?
For modules such as Lib_Magento, Lib_Mage & Lib_Unserialize ,,,etc. I am in version 1.9.2.3 would like to upgrade to 1.9.2.4.
If this is not the correct path please suggest the correct way.

Magento 1.9.2.4. updates the following files from 1.9.2.3:
Without knowing the exact files you mean by "custom files", if any of these files are overridden in the app/code/core or lib/ directory which is considered bad practice, you can copy these to app/code/local before upgrading.
e.g. "app/code/core/Mage/Adminhtml/Helper/Sales.php" would be copied to "app/code/local/Mage/Adminhtml/Helper/Sales.php".
See app/Mage.php and lib/Varien/Autoload.php files for how autoloading works in Magento.
You can also upgrade using shell providing you have shell access and you know how to use shell. I would also test this locally before applying on a live site.
You can download and apply the patch 7405 from www.magento.com/download for 1.9.2.3 to 1.9.2.4 by moving the patch file into your Magento root directory and then from the command line
Then delete the the patch file name.
