These commands will export your data into an LDIF file. Replace everything in the [brackets] with your info.
Change to directory with scripts# cd /usr/lib64/dirsrv/slapd-[TAB]
Dump data to ldif
# ./db2ldif -n userRoot -a /var/tmp/`date +%Y.%m.%d`.ldif
This step might be optional.. I think it should all ready have the 755 permissions when you dump it, but if not, do this...
# chmod 755 /var/tmp/`date +%Y.%m.%d`.ldif
# ./ldif2db.pl -v -D "cn=directory manager" -w PASSWORD -i /var/tmp/`date +%Y.%m.%d`.ldif -s dc=[YOUR],dc=[COM]
