Please specify the version you are upgrading from, it *is* relevant.

Well, maybe you should consider appropriate tuning/changes to your import
process to speed things up, rather than risk data integrity. You don't specify
how large your database is, or any tuning etc., or other slapadd flags, so it
is difficult to know if 1 hour is good or bad.
E.g., using the -q flag to slapadd can speed things up significantly, setting
'tool-threads' in slapd.conf appropriately can too, and you should have
database tuning (e.g. DB_CONFIG) in place.
Starting with different data on providers and consumers is sure to result in

See above, but you provide no detail on what you have done to speed up your
import, and this seems the original problem.
