I migrated my store from Prestashop to Shopify and it was perfect. It took me a few tries to figure out inventory management and such but by the time it was done (you get three "remigrations" in case you want to make changes) it was perfect. I had tried another popular option first and it was awful. Definitely worth every cent especially when dealing with thousands of product entities.
