The most simple and correct way to update the product is to replace the files of the old version of the product with the new version files. All product settings are saved, as they are stored in the database of the website. The second way is to delete the old version of the product, then download and activate the new version. In this case, the product settings may not be preserved, as in many products when they are removed there is a function to clear settings from the website database. Here it is worth noting an important nuance – sometimes developers are releasing a fundamentally new product update with a change in the structure of files, the structure of storing settings in the database, etc. In this case, the product is accompanied by instructions from the developer to switch to a new version, Update to the current version correctly.
