Any way LR 12.5 TruClient scripts can be converted into LR 12.01 TruClient Script?

We have done a lot of work in recording TruClient scripts using LR 12.5, and we need to have this scripts executed by a LR 12.01 controller.  The scripts can not be playback on a LR 12.01 VUGen.  It throws an error on first step:

" Error -205177: ** 1: Navigate to [Exception] ** failed - an argument is invalid: 'Location' : JavaScript exception 'SyntaxError: missing ] after element list'  during evaluation Snapshot Info [MSH 1 0] [MsgId: MERR - 205177] "

Any way LR 12.5 TruClient scripts be converted into LR 12.01 TruClient Script? 

Thanks in advanced.  A solution for this would save us weeks of rework.
