Very basically would you suggest the following

- build new master to match that of current - 5.1 MP6

- migrate to new master

- upgrade new master to 6.0 MP4

This step isn't needed.

- upgrade new master to 6.5.1

- blast old master and make media server

Basically, that's it. One major change at a time so if something fails, you can back out. You don't really want to call Symantec and say "I did a migration to new hardware, a new OS release, and upgraded NBU all at the same time and now it doesn't work".

On Solaris 10, watch the tcp_fusion system parameter. We've found that it has to be disabled on master servers but enabled on media servers.

Log a call before you do your upgrades so they can be ready for you if you do run into problems.
