This seems to be a MySQL question rather than a Perl one.

Having said that, I'll still offer a few comments (which may or may not be helpful)

The information you've provided is a little sketchy, although I believe I have a high-level understanding of what your problem is.

I've faced similar challenges in the past, and the approach I've taken is basically as follows:

  1. Take a dump (mysqldump) of any existing data
  2. Install the new tables
  3. Massage the old data so that it fits into the new table structure
  4. Pump the old data into the new tables.

Of course, all this is done in a test environment before it goes anywhere near a production system. And if step 3 requires anything more than some basic manipulation then I'll usually turn to Perl.

Hope this helps,
Darren :)
