how to move already written codeigniter code to kohana?

Question

Hi, All

I'm already using codeigniter for some time, and i liked it but it looks like i need to move to kohana, because my other team member need our code to fully use PHP5 feature.

the problem is, we have already code half of the code in CodeIgniter. my question is:

1. Did anyone here have done it before?
2. Is it possible to do?
3. how much effort will it take to move the code?

Thank you in advance. and sorry for my bad english.

Update: From abi noda 's answer it looks like i do really need much code rewriting but does anyone have done'it before ? perhaps someone could point me some links?

and yes i thought it is possible to do, but because i don't know how long it'll take time i guess we're gonna keep this project as Codeigniter and move to kohana as soon as next project come to us

Answer 1

See Kohana's documentation - Migrating from CodeIgniter.

A smart fellow from #kohana IRC has informed me that a simple migration no longer exists. Kohana has changed substantially since forking from Codeigniter. They are very different frameworks now, so you would have to rewrite much of your code.

Answer 2

CodeIgniter works well on PHP5.

It is backwards compatible to PHP4, but there is no need to run it on PHP4.

What part of PHP5 is your team not able to use in CodeIgniter?
