Converting From gdbm to bdb

["Brian Gaber" <Brian.Gaber@PWGSC.GC.CA>]

Attempting to convert OpenLDAP v2.0.27-11 configured for gdbm to OpenLDAP v2.2.26 configured for bdb.
 
I have successfully compiled OpenLDAP v2.2.26 and all its prerequisites (Berkeley v4.3.28, etc)
 
I used slapcat on the 2.0.27 server to get a backup of the ldap gdbm database.
 
I run the following command on the 2.2.26 server and get the following error:
 
/usr/local/sbin/slapadd -f /etc/openldap/slapd.schemacheck-off -l /home/ldap-backup/Jul11-0345
slapadd: could not add entry dn="ou=gtis,ou=van1,ou=pac,o=pwgsc" (line=8): txn_aborted! DB_KEYEXIST: Key/data pair already exists (-30996)
 
Here is a copy of slapd.schemacheck-off:
