Oops, if DATA means "DATA":
IFS="."; cat file | while read L; do set $L; if [ "$1" = "CN=DATA" ]; then P=${2#OU=}; echo "CN=${P}_DATA.$2.$3"; else echo $*; fi; done
If DATA is generic:
IFS="."; cat file | while read L; do set $L; if [ "${1%=*}" = "CN" ]; then P1=${1#CN=}; P2=${2#OU=}; echo "CN=${P2}_$P1.$2.$3"; else echo $*; fi; done
