I have 2 carts for our business. One was compromised, and deleted . I have a backup from a week or so ago, with all of the products listed. Normally I would just re-upload the files and be back up and running. But, we were using 1.3.8, and are now using 1.5.0. I do not want to screw up and replace the 1.5.0 files with older versions.

What files/folders do I need to move to get back just the products we had listed (about 3000).

Also, the 2nd cart we have uses the same data base, and all of the items are working properly there. I have not upgraded it to 1.5.0 yet, as I want our main one working properly first.

Would I be better off upgrading the 2nd cart to 1.5.0 and just uploading those files to the main cart?
