Updating CodeIgniter 1.7.3 to CodeIgniter 3.1.7

Your currently at 1.7.3 right? If you follow this link: https://codeigniter.com/userguide2/insta...e_200.html
You can upgrade from 1.x to 2.0. The discussion about if 1.7.3 ever existed or not... we will not go there.
If you update all system files with the files from 2.0.3 (that has always been step 1) you just need to read the upgrade notes from the link above en go through each version until you are at 2.0.3. (Don't test your application until your finished upgrading your code till 2.0.3, because your kernel(system folder) is based off 2.0.3)
I feel you, it's a pain in the ass to go through all the versions. But if you dont want to rewrite the code thats unfortunately your only way to do it.

It's a long way untill you reach 3.1.7! But still, you will get there sometime Wink

Dont forget to adjust your php version as you go through all those versions! Because if you do the upgrade with php7+ you will get all sorts of error's!
