This strikes me as odd. I would at least not want to restart/reimport which
would disconnect the history etc. If you don't want to maintain Solaris 8
support in your new development, you could still create a branch to support
it for old customers etc. I'm not 100% sure what you are doing, maybe if you
explained a bit more people could give better advise.

I believe that applies to BDB, provided the BDB-libs are the same. With FSFS
you should always be able to move the repository without dump/load cycle.

Also, things like merge tracking were improved, I believe. Note that you could
move the repositories to SVN 1.6 while still being able to access the
repositories from 1.4 clients, the old clients just will not benefit from
some of the newer features automatically.

That said, I'd definitely upgrade the server and dump/load the repositories.
