Upgrading CodeIgniter

I finally had an afternoon free, to test the upgrade of the base PHP framework CodeIgniter, on one of my websites.

CodeIgniterThe first operation we need to do (especially if the initial coding started long ago) is to find out which version of CodeIgniter we are currently using.

We need to search for the constant “CI_VERSION” defined inside the code. In my case the starting point was version 1.7.2.

Now we neet to understand which one is the latest version in the download section (currently 2.1.3) of CodeIgniter’s website.

The next step is to find out our upgrade path defined on the upgrade page and to download the required packages.

In my case I downloaded my current version 1.7.2 and the latest 2.1.3.

NOTE: If for any reason you are still running PHP 4, you will not be able to upgrade to CodeIgniter 2.x. It only supports PHP 5.1 and above.

To give you an overview, the presentation starts with an introduction about CRM and why businesses that do not have a CRM strategy should definitely consider implementing one.
