Design a Database Schema of mySQL . Migration of website from perl to cake PHP -- 2

We are migrating one website from PERL to PHP. Now we are using database mysql. But old db that was used has lot of tables and around 2 millions records. In New DB structure needs to be changed. So i need a DB analyst who can review the old db and can make the new DB so that while importing the data from old to new does not cause any problem. Please bid if you are very expert in it
