Convert Inventory BIE Views from 4.3 to 4.5

Howdy,

I have a customer that has about 50 custom BIE views from inventory transactions in 4.3.  In converting the customer to 4.5, the views do show but do not run.  Because the source is still IM5.  Is there a method to open the *.EV file and change the source data to the new inventory table structure?
