Nintex Workflow Not responding

I found the below solution to clear the workflow history

Here are the scripts we need to test in the test environment that will clear the workflow history.  In production I want to clear everything before January 1 2018.  We can be more aggressive than that in test. 

The only thing I ask is that we do not run this against Global Accounting in test.  I need to make sure they are no longer using this data for auditing purposes. 

The production scripts will need to be run off working hours. 

This make take a few days to complete for each site collection.
