Hey -

Is there an upgrade path from 5.3.20 to 6.0.2?  I've been looking for
documentation and the search has fallen short.

Here's some questions that I need answered:

It appears that 5.3.20 clients are able to communicate/function with
6.0.2 servers.  Is this correct?

What is necessary to upgrade the servers?  Is there metadata changes
requiring all data to be copied back?  How about authentication?

Any help is greatly appreciated.
