Yes, this would be possible, but as the slapadd step may take

Well, how much RAM do you have on the system? What is the size of your *.bdb files? To have optimal slapadd -q performance, the size of your BDB cache defined in the DB_CONFIG file should be the sum of all your *.bdb files.

For example on my database:

du -c -h *.bdb

3.3G    total

cat DB_CONFIG set_cachesize 4 0 1 set_lg_regionmax 262144 set_lg_bsize 2097152 set_lg_dir /var/log/bdb set_lk_max_locks 3000 set_lk_max_objects 1500 set_lk_max_lockers 1500 set_flags DB_LOG_AUTOREMOVE set_tas_spins 1

Thank you for your comments. I will revisit slapadd -q and see if I can make it go fast enough and escape my wish for binary copies across platforms.
