I would recommend 'svnadmin upgrade' instead of dump/load, unless you
are already having specific problems addressed by new features which
require a dump/load to be effective for existing revision data.

So if, for example, the size or the number of files in your existing
repositories does not bother you, there is no point in wasting time
for a dump/load cycle. 'svnadmin upgrade' takes virtually no time at all.

You may even choose not to upgrade your repositories at all.
They will continue operating like they did with a 1.4 server.
But you will again be running a supported server version which receives
bug fixes in point releases, and newly created repositories will use
the new features automatically.
If users of existing repositories do not need the new features
offered by an upgrade then this is probably your best option.
