Need to move products from another store

I have 2 carts for our business. One was compromised, and deleted :censored: . 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?

Categories and products are stored in the database, and not in files, so if both sites are using the same database, the products should be there.

That is what I originally thought, but I could not figure out why they do not show up.

Could the difference in Zen Cart version prevent the database files from working with both carts?

Just to be absolutely clear:

Do you mean the sites contain the same INFORMATION? (IE: when you add a product to site #1, you then go to site #2 and add it there too)?

Do you mean both sites operate off a SINGLE DATABASE ON THE SERVER? (IE: if you add a product to site #1, it magically ALSO appears on site #2)?

Option #2, Single Database

Absolutely.

The PHP code expects the database content to be of a certain structure. You cannot mix versions of code and expect things to work without problems.
