Some words about updating OpenLDAP

To put it simply:
Don't
After all the problems I've run into while updating an OpenSUSE server from 8.something to 11.0, I think it's not doable. I think the best route is to backup the data through an LDIF dump, remove OpenLDAP, upgrade the system, reinstall OpenLDAP, do the first configuration and upload the LDIF data.
I think that, for a small system, it is not worth the effort.
I am sure that somebody will swear by OpenLDAP, and am almost certain that, if I were a full-time system administrator, I would be one of them.
