I think you may have taken this quote out of context. Repository
sharding is transparent to the client, only the server libraries will
ever see the sharded directories. If you're using file:/// access,
then the client is also the server, so you'll need matching version
numbers in that case.

All 1.x clients are compatible with all 1.x servers. When one is older
than the other, the newer features will be disabled for the operations
being performed. If you have some people doing merges with 1.5 clients
and your 1.5 server, and others doing merges with 1.4 clients and your
1.4 server, things could get a little messy.

Yes, you should be able to do that upgrade. The existing revisions
will not be sharded (IIRC there's a python script that'll do it), you
won't get the improved diffing algorithm (which *may* save you a bunch
of space on the server), and you'll also need to run
svn-populate-node-origins-index per the release notes.
If you do the dump/load cycle, that will all be taken care of for you.
