How to upgrade magento to 1.8

Magento 1.8 has been released with,

  • Major overhaul of tax calculation formulas, correction of rounding errors, and additional assistance with configuration.
  • Optimized cache adapters for single-server systems.
  • Upgraded Redis cache adapters for multi-server systems.
  • Eliminated many types of database deadlocks.
  • And many more updates and changes………..

Now, Magento developers get a new JOB to upgrade magento from older version to magento 1.8.

Magento recommends you upgrade your installation using the following guidelines in a development or test environment, separate from your existing production environment:

  1. Create a parallel development or testing system, identical to your current production system.
    • You’ll use this parallel system to implement and test the Magento upgrade.
  2. In your current production environment:
    • Back up your Magento database.
    • Archive the file system. This includes the media directory and subdirectories; all extensions and customizations; and all custom themes.
  3. In the development or test environment:
    • Create a new, empty database instance.
    • Import the production database tables into the development database instance.
    • Copy your production media directory, extensions, themes, and other customizations to the development system.
    • Copy local.xml to magento-install-dir/app/etc and edit it if necessary to reference the production database instance.
    • In a web browser, go to your development system base URL.
    • Wait for upgrade scripts to run.
    • Verify the development system is now identical to the production system.
    • If not, fix issues, retest, and upgrade again.
  4. Test the development system thoroughly, including:
    • Verify all extensions, themes, and customizations work.
    • Place orders using all webstores and all payment methods.
