Hello.

If you did any customazation or made your own plugins you will have to upgrade those yourself.

The link pasted in the post above is just information about how YOUR plugins should communicate with the db from version 4.3.

In order to upgrade from 3.7 to 4.3 you have to replace all the code. Usually I delete all files in the project(except what's customized), and then I paste the new code into the solution. This way your sure old files which isn't used anymore is removed.

After that I upgrade everything I've created plugin by plugin. This is usually quite time consuming.

When that's done, and your solution is building, you have to upgrade the DB with SQL scripts. You can find them here: https://github.com/nopSolutions/nopCommerce/tree/develop/upgradescripts

You have to execute 3.7-3.8, 3.8-3.9, 3.9-4.0, 4.0-4.1, 4.1-4.2, 4.2-4.3. Some of these will take a LONG time.

You also have to run sql scripts for your theme, if you are using nop-templates.

Good luck!
