New version of custom module was updated. How to mode data?
I have custom module built based on products sample. Sometimes, this module fields/links get updated and I do clear re-installation of module. How I can copy over data from old module to new one? Manually it takes a lot of time. Can I connect to both databases (old and new) at the same time and use API to get old module items and construct new ones?
+ Some fields are image links how would I copy over images using API.
Thanks.
