One should generally be careful with system upgrades.
Esp. major version jumps.
AFAIK on-disk-format might change because of Berkeley-DB version upgrade.
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 what I did when I upgraded a old server running CentOS 5 to a new
server running CentOS 6.)
But without knowing about the backend configuration used it's impossible to
track this down.
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
