Moving from Codeigniter 3 to Codeigniter 4 - Dina_Az - 12-05-2021
Hello!
We have a web app which is written in Ci3. I have gone through the Ci4 docs and a lot has changed and its going to be a lot of work to get the migration working.
My question is ----- In ci4 I noticed that a model represents a row and you can put db restrictions etc. However, we have not done it that was in ci3 (don't think this feature was there) so, if we were to move our model functions over and do the right naming etc. do you think this will work?
I am trying to gauge how much work will be involved in the migration. I guess I am going to try it over the weekend but I thought I'd ask here as well just in case someone has done the migration.
So, move our files over. Change naming conventions and how views are called etc...is that the minimum work required?
Thanks in advance!

It is a package that provides CI3 compatible interfaces.
If you use it, you might go to CI4 quickly. It is not the official and does not support full CI3 API.
If you want to know the real tasks to migrate CI4, reading the latest user guide helps you.

And I recommend you try to migrate one controller.

Can you explain a little bit more how to use this? I download your file and I have my file...then I do what exactly? I'm so new and I have so much to learn.

I've taken a job and their website guy is AWOL, but they want a new client portal so here I am tossed into the newness of web design.
