Solution:-

In the current directory from where you are running the adop parepare command check if any older DBC file exist, if so remove or move it to some backup folder.

And retry the command.

applprod@panserver:/home/applprod>> mkdir dbc_backup

applprod@panserver:/home/applprod>> mv pansoft_prod.dbc_1202 PROD.dbc dbc_backup
