Which suggests that one needs to dump the 12.04 database (to ldif text format) and then reload it into the fresh 14.04 database.

This is the reason *RedHat* Enterprise Linux is never recomended to do upgrades across major versions. The recomended practice is allways a fresh install. (Of course, RHEL has a much longer lifetime and package APIs generally make a *big* jump.) Ubuntu has a shorter life span, so things *generally* don't make such a big jump, but it looks like that is not always the case. > > Ciao, Michael.
