Can we update asset number in completed work orders in EBS r12.2.11 version

Please note, the asset was already sold and cancelled registration plates on 21/03/2019 and in the system showing “discontinued”.   We have same plate number for one of our MAN truck “MANTRK83781”  which is active truck and available in workshop oracle portal. 

While creating job cards for  “MANTRK83781”  were created on cancelled similar asset by mistakenly.  Both asset numbers are existing “83781” and “MANTRK83781” in workshop portal, but actually needs to show only “MANTRK83781” which truck is active now.

We seeking your support to transfer whatever job cards were created on sold vehicles (83781) will transfer to MANTRK83781 which is active vehicle.  Then delete 83781 from workshop oracle portal which is already sold.
