[ILUG-BOM] Upgrade Novell 4.11 to Samba 3.0.7 wisdom needed

Has anybody done such a thing as this? I'm looking to make this transition as smooth as possible. I have the new fileserver up and running, and I'm using rsync to keep the Novell data current on the Samba server. Any words of advice on transferring the users and groups and permissions over to the new server in the least painful way possible? I have some idea that Novell uses LDAP so that I should be able do it somehow. I don't want to screw this upgrade up, and any help would be appreciated. I am hoping someone has already done it before and has written a Howto or something about it.

Thanks,

Komal

PS My version of Novell is 3.11 and 4.11
