The original poster did a significant distribution upgrade and not just a package upgrade. While there might be distributions which have some sort of upgrade magic I strongly recommend that everybody should follow the standard slapcat/slapadd procedure when doing significant upgrade. And of course do a backup right before upgrade after turning down writing to the directory. Everything else I would not trust enough for a serious deployment. Ciao, Michael.
