Frankly, this all begs the question of why you are putting important long-term data in Apache::Session. That isn't what it's for. You should only have transient data in there. I don't think you'll find any clear upgrade path that maintains the data, so you either hav to write your own data migration script or not upgrade Apache::Session. - Perrin
