I've taken over finishing a webstore that someone else started to create. I'm learning as I go along. It currently has WooCommerce, but as we plan on using SagePay thought it might be in my best interests to switch to Ready! but if I install it will I have to re enter all of my inventory? What exactly will happen if it dumps WooCommerce will I lose everything? This is not a matter where I think trial and error is the way to go.
