Thank you Ed.

I do appreciate the response. The Technote does indeed talk about the
upgrade process being Master / Media / Clients in this order. I guess I was
trying to find a possible "in-trim" work around to upgrade the Master and
upgrade this single client to MP5 (which is LAN Based client) to prove all
is ok. (without affecting the SAN Media Servers straight away and buy some
time).

But if the Business do not allow the downtime, there are no real options
open here! And worse case Ed, I can revert the entire system back using a
snap-shot based system which only takes 5 mins to do and 10 to revert back!

Will keep the list posted if I try this the unsupported way. (although I
know its unlikely I will receive any help!).

Most definitely not supported.  The master needs to be at the highest 
rev, followed by the media servers, and then lastly the clients. 
Upgrading a client to a version later than a media server is a no-no.

If you have any issues, you will not be supported.  Whether that is a 
risk you're willing to take is up to you.  Whether it works or not is 
something you may not get good feedback on since most (hopefully all) of 
us don't run configurations that are documented as unsupported.   You 
could have some fun SSO issues that you're simply not going to get any 
help on...
