What options are there for writing Unit Tests on code that performs mass database updates

I have code in a very old desktop application that I am converting to C#. It runs a billing cycle and I have a test database that performs the update on around 5000 rows of data.

I can take a copy of the database, run it with the desktop application and run it with my code and perform a compare with SQL EXCEPT to make sure my new code is producing exactly the same results as the the desktop code.

This is fine for running manually, but it would be nice to somehow automate this, and indeed to add it to our development environment so it can be run regularly as part of our suite of unit tests, together with various tests using different settings.

I'm not familiar with this sort of testing - I usually just run with very limited amounts of data where the unit test creates the data, runs the test, then deletes the data again, or just uses NSubstitute to simulate data persistence.

We use a Microsoft SQL Server database 2008 and later.

So any thoughts, suggestions, articles, ideas would be welcome.

Thanks.
