This is a very complex task and as far as I know many have tried to solved it so far (unfortunately I am not aware of any 100% guaranteed solution).

I'd say that before jumping to implement your own solution you should take a look and read about the challenges you'll be facing by reading about Schema evolution, Schema Refactoring, Schema versioning, etc.

Afterwards, you can take a look at PHP MDB2_Schema (some more documentation in this article).

If you are not tied to PHP then you may also take a look at Sundog which provides a set of advanced schema refactorings.

Once you get a reliable schema migration tool for your app, migrating data will be just a trivial task.
