It is quite likely that your database got corrupted somewhow, so
depending on the database definition you may try to recover the data
first. If you had defined 'database bdb' in slapd.conf you may try to
recover the database with the BerkeleyDB tool db_recover, if you had
defined database ldbm, you lost.
To add a database to a new OpenLDAp instance the proper way is to dump
the old data to a file, using the tool slapcat(8) and slapadd(8) to
the new instance. As you presumably have built OpenLDAP with a newer
version of BerkeleyDB, just copying files is not appropriate.
