I dont have any audit programs but my number one recommendation is data integrity...before and after conversion. Make sure the departments (loans, deposits, accounting) do enough sampling and testing before hand. It will make a world of difference. We didnt do enough and are still finding data integrity issues a year later.
Also, sit in on as much training as they'll allow. It helps to address control issues up front instead of after the fact.
I don't need any more negativity in my life...be positive and helpful people or I will kick you in the shins!!!
