Thank you for the reply!

I'm still a little confused. It appears what you showed was if I had one deposit that I needed to go back in time and change classes on, I could use that method, which I get. But my situation is that I had multiple deposits over time and multiple expenses that came out of that fund and now the class still has money assigned to it as a "balance" and the project is over. I would like to move the balance of the funds assigned to that class and put it in the balance assigned to another class. 

As an example, I had ten deposits and ten expenses over time tagged with the "HVAC" class. That class currently shows a "balance" of $200 when I run reports by class. The balance happened as a result of the net difference between the ten deposits and ten expenses. But that HVAC project is now over and I want that $200 to show as part of the balance of another class and then inactivate the HVAC class. That is the transaction I'm looking to accomplish.

I hope I am making sense... thank you for your help!
