I am cleaning up from my predecessor. Unfortunately, the workflow is inefficient and runs more times than necessary, creating a workflow history list of 450,000 items in a short time.
Before I can fix the workflow, I need to fix the Workflow History List, which we all know is not "cleaned" by the ridiculous WF cleanup timer in CA.
Should I just edit the workflows to point to a new workflow history list, and then delete the entire default list? I have already seen this: How to delete a Workflow History list?
