Here's what I did:
1. Uninstalled DS 1.4 and installed 2.0 from EPEL. This got me the entryuuid plugin.
2. Made a copy of slapd.d and exported the database to LDIF (using slapcat). Instructions for this can be found at:
https://directory.fedoraproject.org/docs/389ds/howto/howto-openldap-migration.html .
3. Used ol-schema-migrate.pl to convert our OpenLDAP schema file to DS, and copied the new file to /etc/dirsrv/schema. I found the script at
https://directory.fedoraproject.org/docs/389ds/howto/howto-openldapmigration.html .
4. Created a new DS instance using all the defaults, except:
- changed the instance name to one that represented my LDAP database purpose
- changed the suffix to match the suffix from my OpenLDAP database.
5. Removed unneeded and problematic OpenLDAP replsync entries from my LDIF export:
- entryCSN
- contextCSN
6. Used ldapadd to import the LDIF.
- ldapadd -x -D "cn=Directory Manager" -W -f myexport.ldif
Everything imported, and I now have a test copy of our LDAP DB in 389-DS!
Typing this up has me thinking though, since entryuuid is also just an OpenLDAP implementation, I should be able to remove that from my LDIF. Does anyone disagree with that? I need to give that a shot...
Thank you again Mark and Paul, and hopefully, this will help anyone else struggling with an OpenLDAP to 389-DS migration.

Mark,
Thanks for that. I have gone through those docs already, and I'm still running into it. My 389-ds-base package is version 1.4.4.17.

What version of 389-ds-base are you using?
Check out these docs if you haven't already:
https://www.port389.org/docs/389ds/howto/howto-openldap-migration.html

Thanks,

After RHEL, etc dropped OpenLDAP, I've begun testing with 389 Directory Server. Currently, I'm trying to use openldap_to_ds to import slapd.d config and an LDIF export to import my old database into the new server.
I've created a new instance in 389-ds named terminal-config. I've tried the following variations on the idea, all of which gave me the same results:
1. exported the LDIF from OpenLDAP 2.4 on Oracle Linux 7 and CentOS 6 servers.
2. Rewrote all files being imported to make sure they weren't corrupt.
3. used relative and absolute path names to the files
4. Tried importing with a new instance (as mentioned above) and no instance at all
5. When using dscreate to make the new instance, I've tried setting it up differently (allowed sample entries and not, etc)
No matter what I do, this is what I get when I try:
[root@ldaptest ~]# openldap_to_ds terminal-config /root/slapd.d /root/terminals.ldif
Examining OpenLDAP Configuration ...

During handling of the above exception, another exception occurred:

log.error("Error: %s" % " - ".join(str(val) for val in msg.values()))

[root@ldaptest ~]#
Any thoughts on what could be causing this?
