Hi Adeel,

You have to first upgrade DB from 3.8 to 3.90, 3.90 to 4.00, 4.00 to 4.10, 4.10 to 4.20, 4.20 to 4.30
and then update/replace your code/files with nopCommerce 4.40.0/4.40.2. This will automatic update your db to 4.40.0 compatible as auto migration added in code.

Hello rajupaladiya, it's not really clear for us how to use "automigration"
For instance, we need to upgrade 4.40.1 to 4.40.2... what should we do? Just replace files? Is there any way to replace ONLY updated files?
