Downgrading Magento

Question

I'm using Magento 1.4.1.1 for my webstore. The payment processor supports only 1.4.0.0. I realized this only just now when I was dreaming up of opening the store. Duh! Poor planning.

What's the way out?

Will downgrading help? Wat are the implications of that?

Thanks for any and all inputs.

Answer 1

I am not aware of anyone ever having successfully downgraded Magento. That said, a few considerations:

• Are you using version control like you should be? If so, you should have a copy of the site and database from just before the upgrade. You should be able to use this as a starting point. This is your most optimistic route by far.
• If no version control, you can download both of the versions and use diff to get the changes. Doing this in reverse theoretically creates a backwards patch.
• If you've stayed out of the core code entirely, the code change could be nearly as simple as replacing app/code/core.
• Even if you do downgrade the code, the data structures between versions have probably changed, so you'll need someone experienced to find those changes and tell you have to back-patch your database. This is, to say the least, perilous.

Overall, I wouldn't want to undertake this task. As Anton said in the comments, you'll probably have an easier time getting integration done than reverting the changes.

Best of luck!
