I've to move a lot of products from an old Magento site (v. 1.4) to a new one (1.7) with fresh new theme with new modules it's also a multisite, infact there' already a lot of stuff I configured in order to make it work right. so if I change the database it probably will stop working.
So, before start moving... what do you guys suggest me is better. Move only the Products + images or move the entire database? I read a lot of docs. And saw it's a long work upgrading Magento from such an old version to a newer one. Plus at the end the stuff I guess, I need from the old site are only the products and maybe some info like name, phone etc. (but that could be added by hand)
what you think I should do?!
