I agree with Eric and I have 8.2 VE setups connected to 7.1 servers at
multiple sites, i've never seen any issues. I do find the documentation
strange if it say's you need to upgrade your clients before upgrading the
server. The only thing that makes sense to me is client-side dedup with
compression, for that you want your clients on the latest level otherwise
the compression isn't compatible with the server compression and you don't
get optimal results.
