If you have the space, why not just partition your array? Depending on the
filesystem you might even be able to shrink a partition without going
through a backup/restore.

Of course, I too recommend upgrading... but if you have a lot of
development into your custom frontend and whatnot, it may not be something
you can do in the short term... so shrink for short term then perform your
upgrade in a test environment until its ready for release.
