We are getting ready to upgrade from nopCommerce 3.4 to 3.7 and are wondering if we need to worry about saving our Store Locator information prior to starting the upgrade process. Where is the locator information stored?
This information is stored in your database, so you will just have to run both upgrade scripts. To be 100% sure that you don't loose any information our advice is to backup the database before you start running the scripts.
p.s. I see that you are upgrading from version 3.4 to version 3.7. Don't forget that you have to run first the upgrade scripts for 3.5, then for 3.6 and then for 3.7.
