I have to upgrade a Magento 1.9.1 store to 1.9.4 to work with PHP 7.2.
What I did was clone the store on a temporary server and update everything there. The store now works fine, but the update took a few days and now there are some new customers and orders.
During the update, I also update some extensions to a new version.
My question is if I now only export the 1.9.1 database and import it to the 1.9.4 database, will this work smoothly and update itself or could there be some problems since the database was not updated when updating to 1.9.4? and new extensions were installed.
Would it make more sense to discover how to update customers and orders?
