OK, thanks!
It would be awesome if that kind of information would be in the 389DS
homepage, FAQ section.
Or a HOWTO that explains migration process to a newer version of 389DS
in a working replication environment.

Do you not want any new features? RHEL 5 was released in 2007.

Right. The way we recommend it in FreeIPA is to set up a new master on the
new OS, get replication done, then shut down the old side. Bingo, you're on
the new version with the same data. In practice it might be a little more
bumpy than that, particularly if you want to run them in parallel for a
while, but we've been consumers of 389-ds for 6+ years and haven't had many
issues in differing versions.
