Re: V5r4 Upgrade

[Jim Oberholtzer <midrangel@xxxxxxxxxxxxxxxxx>]

Rob,

You'll argue that Larry, Pete, and I do this all the time (as well as 
several others on the list that regularly contribute) so it's simple to 
us.  True, but it's not all that advanced.  If your unsure about the 
system administration bits, get some help for a couple of days.  It's 
well worth the investment, and I often get IT Directors to use the 
educational funding for it, since I teach the techniques while we do 
it.  Now the skills stay and you have a well set up system.
