Introducing Migrations to CodeIgniter

[eluser]barbazul[/eluser]
It's my bad I mixed an example using the dbutil helper (which i never released) with the las release.
Anyway I have abandoned the db util helper since there is a dbforge library that can take care of all the hard work with database maintenance.
So i'd suggest you adapt the examples to make it work using that implementation instead

let me know if you need any help doing this
