Help with the first migration, you want to rename the fields and make them not zeros

Question

My current schema looks like this:

create_table "users", :force => true do |t|
    t.string   "username"
    t.string   "firstname"
    t.string   "lastname"
    t.datetime "loggedin_at"
    t.datetime "created_at"
    t.datetime "updated_at"
    t.integer  "user_status"
  end

I want to rename "username" to "username" and make all the fields non-empty (they can be reset now).

How should I do it?
