Nice try, but I hope nobody follows the template below.  Having been heavily
involved in a Windows to Solaris migration back in 3.4, I can tell you it's
a lot more complicated than this.  If you have to ask for how to do this
migration, honestly, you don't have the skills to complete it.  

The short answer is to get professional help.  If you don't know what you're
doing, you'll corrupt the works, lose backups as you revert, and generally
create a huge mess for yourself.  You've got both the image catalog and the
volume database to deal with.  You can't do one without the other.

Along with the fun stuff that Curtis documented below, you'll run into files
that are over 2GB that unix2dos won't handle, and internal references to the
master server name.  It's non-trivial and you'll watch NBU break in weird
and wonderful ways when you try.  

When we did a *media server* rename with a Level 3 person on site (and this
was on 6.0MP4), it still took us several hours and a call to engineering
before we gave up and left it the old name.
