Create a minimal slapd.conf with a database mdb configuration with a
different directory path.
slacat the bdb database,
slapadd -f path/to/minimal/slapd.conf -l ldif file

ldapmodify
dn: olcDatabase={1}hdb,cn=config
changetype: modify
replace: olcDatabase
olcDatabase: {1}mdb
-
replace: olcDbDirectory
olcDbDirectory: /path/to/newDB

Instead of slapcat and a minimal slapd.conf you may dump the database
by ldapsearch, modify the config database as above and ldapadd the
dumped file.
