Hello,

Goal:
I want to upgrade nopCommerce to the latest version.

Background:
1. I have installed nopCommerce 4.20 via Azure Marketplace. Therefore, I do not have access to files and database locally, but they are accessible via Azure.
2. Before attempting upgrade, I also want to create a running clone of the website (in case anything goes wrong).

Problem/Question:
I have followed information available in the documentation and forum to copy the website. However, I get a database error in the cloned version, and it does not work at all. Here is the error:
"Cannot insert the value NULL into column 'Id', table 'xxxxxxxxx.dbo.Log'; column does not allow nulls."
How can I safely (clone and) upgrade my website? Thank you very much in advance for your help.
