I'm hoping someone can help me with this, but I am getting an error attempting a cross migration from an old version of FDS (FDS 1.0.4) on CentOS 4 32bit to current 389 Directory server (via yum repos) on centOS 5.4 64bit. I used the following in order to install 389 DS on my new CentOS server 5.4 64bit : http://directory.fedoraproject.org/wiki/Download#Enterprise_Linux_5

I've exported my databases to LDIF as directed in the documentation as well and am performing the migration on the new server from a tarball of the original install taken from the old server.

Anyway, when I run the migration script here is the output error I get.  How do I correct this (I'm no LDAP expert that is certain)?

I'm not sure how to troubleshoot this. Any help would be great.
