shell script
Code:
DIR=/your/directory
for FILE in $(ls $DIR)
do
 OLD_DT=$(echo ${FILE##*_} | cut -d. -f 1)
 NEW_DT=$(expr substr $OLD_DT 5 4)$(expr substr $OLD_DT 1 4)
 RENAMED_FILE=$(echo ${FILE%_*})"_"${NEW_DT}"."$(echo ${FILE##*.})
 echo mv $DIR/$FILE $DIR/$RENAMED_FILE
done

Replace the red marked /your/directory with the directory name where you have the files.

After reviewing the output you may remove the red echo and execute for renaming files.
