What version of CI am I running - vdvn - 09-14-2015
Hi all,
I am new to CodeIgniter and I have been handled a legacy system using CI. I am wondering where can I find what CI version the system is using? I opened a few php files and although they all have a version number in them there seem to be several different numbers.
Granted, it seems like I inherited a 1.x version. So I am also wondering if it's worth it to migrate to the latest version (3.0.1)? And what kind of hurdle I should expect?
Thanks for the help

For your version you can have a look at system/core/CodeIgniter.php Or you can use "echo CI_VERSION;".
You can read the documentation about upgrading process:
http://www.codeigniter.com/userguide3/installation/upgrading.html
Probably the most relevant ones are:
http://www.codeigniter.com/userguide3/installation/upgrade_200.html
http://www.codeigniter.com/userguide3/installation/upgrade_300.html
I believe all the upgrades from 2.0 tot 2.2 all just involve replacing the system dir, no need to change your own application.

To check CodeIgniter version you can use
PHP Code:
echo CI_VERSION;
in some of your controllers. Remember, that echoing directly from controller is a bad practice, but for this purpose it is good enough.
