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 
broken replication.

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